Instantiate and InstantiateLazy have the same signature; on first
principles, if Instantiate should work for importers it should be
possible to consolidate these APIs.
This CL does this. In order to make it work, a typMap needs to be
threaded through type expansion to prevent infinite recursion in the
case that the Checker is nil.
Notably, Named types now must be expanded before returning from
Underlying(). This makes Underlying generally unsafe to call while type
checking a package, so a helper function safeUnderlying is added to
provide the previous behavior. This is probably overly conservative at
most call sites, but cleanup is deferred to a later CL.

*Named types
Now that the pointer identity for a *Named type doesn't change
anymore when going from lazy instantiated to actually instantiated
(= expanded) state, expand() only needs to be called when we deal
with *Named types and only if we care about a *Named type's internals.
Remove the expand function and respective calls for all types and
replace with specific t.expand() method calls where t is a *Named.

lists
This CL resolves several known issues and TODOs.
- Represent type sets with term lists and using term list abstractions.
- Represent Unions internally as a list of (syntactical) terms.
Use term operations to print terms and detect overlapping union
entries.
- Compute type sets corresponding to unions lazily, on demand.
- Adjust code throughout.
- Adjusted error check in test/typeparam/mincheck.dir/main.go
to make test pass.

for interfaces
With this change, interfaces are "completed" on-demand, when needed,
and the respective information (set of all methods, type constraints)
is recorded in a new typeSet data structure.
As a consequence, interfaces don't need to be explicitly completed
anymore and (internal) uses of interfaces have become much simpler.
This change also introduces a new field Interface.complete to indicate
that all methods and embedded elements have been set up. This prevent
the computation and recording (!) of a partial type set for erroneous
programs (if we compute the partial type set and store it, subsequent
type set accesses use the wrong type set which may lead to follow-on
errors).

Deal with export/import of recursive generic types. This includes
typeparams which have bounds that reference the typeparam.
There are three main changes:
- Change export/import of typeparams to have an implicit "declaration"
(doDecl). We need to do a declaration of typeparams (via the
typeparam's package and unique name), because it may be referenced
within its bound during its own definition.
- We delay most of the processing of the Instantiate call until we
finish the creation of the top-most type (similar to the way we
delay CheckSize). This is because we can't do the full instantiation
properly until the base type is fully defined (with methods). The
functions delayDoInst() and resumeDoInst() delay and resume the
processing of the instantiations.
- To do the full needed type substitutions for type instantiations
during import, I had to separate out the type subster in stencil.go
and move it to subr.go in the typecheck package. The subster in
stencil.go now does node substitution and makes use of the type
subster to do type substitutions.
Notable other changes:
- In types/builtins.go, put the newly defined typeparam for a union type
(related to use of real/imag, etc.) in the current package, rather
than the builtin package, so exports/imports work properly.
- In types2, allowed NewTypeParam() to be called with a nil bound, and
allow setting the bound later. (Needed to import a typeparam whose
bound refers to the typeparam itself.)
- During import of typeparams in types2 (importer/import.go), we need
to keep an index of the typeparams by their package and unique name
(with id). Use a new map typParamIndex[] for that. Again, this is
needed to deal with typeparams whose bounds refer to the typeparam
itself.
- Added several new tests absdiffimp.go and orderedmapsimp.go. Some of
the orderemapsimp tests are commented out for now, because there are
some issues with closures inside instantiations (relating to unexported
names of closure structs).
- Renamed some typeparams in test value.go to make them all T (to make
typeparam uniqueness is working fine).

This CL adds three new functions to the types2 API to support lazy
import resolution:
1. A new Scope.InsertLazy method to allow recording that Objects exist
in a particular Scope (in particular, package scopes) without having
to yet fully construct those objects. Instead, types2 will call the
provided `resolve` function if/when the object is actually needed.
2. Similarly, a new NewTypeNameLazy function to create TypeName
objects without yet instantiating their underlying Named
instance.
3. Finally, an InstantiateLazy method, that allows creating type
instances without requiring any of the types to be expanded right
away. Importantly, this requires providing a types2.Checker argument
to handle recursive types correctly.
The APIs as-is are a bit clumsy (esp. NewTypeNameLazy), but seem to
work well for cmd/compile's needs. In particular, they simplify some
of the complexities of handling recursive type definitions within the
importer.
Also, the current prototype is a bit fragile. It uses sync.Once to
manage concurrent lazy resolution, which is frustrating to debug in
the presence of reentrancy issues. It also means the importer needs to
deal with concurrency as well. These aren't issues for types2 though
as cmd/compile only walks the type-checked AST sequentially.
Finally, it looks like some of the details of lazy type names are
similar to the lazy "instance" stuff used for generics, so maybe
there's opportunity for unifying them under a more general (but still
internal) lazy type mechanism.
I had originally intended for this CL to also update the types2
importer, but (1) it doesn't have access to the types2.Checker
instance needed to call InstantiateLazy, and (2) it creates a new
TypeName/TypeParam at each use rather than reusing them, which
evidently works with types2.Instantiate but not
types2.(*Checker).instantiate (i.e., InstantiateLazy). I spent a while
trying to fix these issues, but kept running into more subtle
issues. Instead, I've included my WIP "unified IR" CL as a followup CL
that demonstrates these Lazy methods (see noder/reader2.go).
Updates #46449.

- We still mostly ignore the tilde information.
- More consistent naming: A Union term is the pair (type, tilde).
Rename Union.terms to Union.types; the Union.types and Union.tilde
slices make up the Union terms.
- Replace Sum.is with Union.underIs: underIs iterates through all
union terms and calls its argument function with the underlying
type of the term (and thus can ignore the tilde information).
This also eliminates the need to call under in the argument
function.
- Added Union.is for situations where we need to consider the tilde
information for each Union term.

Accept embedded interface elements of the form ~T or A|B and
treat them like type lists: for now the elements of a union
cannot be interfaces. Also, translate existing style "type"-
lists in interfaces into interface elements: "type a, b, c"
becomes a union element "~a|~b|~c" which in turn is handled
internally like a type list.
For now, "~" is still ignored and type lists are mapped to
Sum types as before, thus ensuring that all existing tests
work as before (with some minor adjustments).
Introduced a new Union type to represent union elements.
For now they don't make it past interface completion where
they are represented as a Sum type. Thus, except for printing
(and the respective tests) and substitution for interfaces,
the various type switches ignore Union types. In a next step,
we'll replace Sum types with union types and then consider
the ~ functionality as well.
Because union elements are no different from embedded interfaces
we don't need a separate Interface.types field anymore. Removed.

working
The general idea is that we now export/import typeparams, typeparam
lists for generic types and functions, and instantiated types
(instantiations of generic types with either new typeparams or concrete
types).
This changes the export format -- the next CL in the stack adds the
export versions and checks for it in the appropriate places.
We always export/import generic function bodies, using the same code
that we use for exporting/importing the bodies of inlineable functions.
To avoid complicated scoping, we consider all type params as unique and
give them unique names for types1. We therefore include the types2 ids
(subscripts) in the export format and re-create on import. We always
access the same unique types1 typeParam type for the same typeparam
name.
We create fully-instantiated generic types and functions in the original
source package. We do an extra NeedRuntimeType() call to make sure that
the correct DWARF information is written out. We call SetDupOK(true) for
the functions/methods to have the linker automatically drop duplicate
instantiations.
Other miscellaneous details:
- Export/import of typeparam bounds works for methods (but not
typelists) for now, but will change with the typeset changes.
- Added a new types.Instantiate function roughly analogous to the
types2.Instantiate function recently added.
- Always access methods info from the original/base generic type, since
the methods of an instantiated type are not filled in (in types2 or
types1).
- New field OrigSym in types.Type to keep track of base generic type
that instantiated type was based on. We use the generic type's symbol
(OrigSym) as the link, rather than a Type pointer, since we haven't
always created the base type yet when we want to set the link (during
types2 to types1 conversion).
- Added types2.AsTypeParam(), (*types2.TypeParam).SetId()
- New test minimp.dir, which tests use of generic function Min across
packages. Another test stringimp.dir, which also exports a generic
function Stringify across packages, where the type param has a bound
(Stringer) as well. New test pairimp.dir, which tests use of generic
type Pair (with no methods) across packages.
- New test valimp.dir, which tests use of generic type (with methods
and related functions) across packages.
- Modified several other tests (adder.go, settable.go, smallest.go,
stringable.go, struct.go, sum.go) to export their generic
functions/types to show that generic functions/types can be exported
successfully (but this doesn't test import).

Especially with typesets, we should be able to fully represent a
typeparam bound as just another type (actually an interface type).
Change the representation of a typeparam in types1 to include a bound,
which is just a type. Changed the signature for NewTypeParam() to take a
sym, and not a package, since we always set the sym (name) of the
typeparam when creating it. No need for an extra pkg field in Typeparam.
Also added index field in the types1 representation of typeparam. This
is especially needed to correctly export the typeparam, and re-import it
as a types2 type (which requires the index to be set correctly).

properly. To get it all working, this change includes:
- Add support for substituting in interfaces in subster.typ()
- Fill in the info for the methods for all instantiated generic types,
so those methods will be available for later typechecking (by the old
typechecker) when assigning an instantiated generic type to an
interface. We also want those methods available so we have the list
when we want to instantiate all methods of an instantiated type. We
have both for instantiated types encountered during the initial noder
phase, and for instantiated types created during stenciling of a
function/method.
- When we first create a fully-instantiated generic type (whether
during initial noder2 pass or while instantiating a method/function),
add it to a list so that all of its methods will also be
instantiated. This is needed so that an instantiated type can be
assigned to an interface.
- Properly substitute type names in the names of instantiated methods.
- New accessor methods for types.Type.RParam.
- To deal with generic types which are empty structs (or just don't use
their type params anywhere), we want to set HasTParam if a named type
has any type params that are not fully instantiated, even if the
type param is not used in the type.
- In subst.typ() and elsewhere, always set sym.Def for a new forwarding
type we are creating, so we always create a single unique type for
each generic type instantiation. This handles recursion within a
type, and also recursive relationships across many types or methods.
We remove the seen[] hashtable, which was serving the same purpose,
but for subst.typ() only. We now handle all kinds of recursive types.
- We don't seem to need to force types.CheckSize() on
created/substituted generic types anymore, so commented out for now.
- Add an RParams accessor to types2.Signature, and also a new
exported types2.AsSignature() function.

The changes between (equivalent, and reviewed) go/types/type.go
and type.go can be seen by comparing patchset 1 and 3. The actual
change is just removing the "// UNREVIEWED" marker and some
comment adjustments.

favor of function
This removes the need for the aType embedded type and brings the types2.Type
API in sync with the go/types.Type API.
For reasons not fully understood yet, introducing the new under function
causes a very long initialization cycle error, which doesn't exist in
go/types. For now, circumvent the problem through a helper function variable.
This CL also eliminates superflous (former) Under() method calls
inside optype calls (optype takes care of this).
Plus some minor misc. cleanups and comment adjustments.

methods with functions
This removes two more converter methods in favor of functions.
This further reduces the API surface of types2.Type and matches
the approach taken in go/types.

than methods
This change replaces methods with functions to reduce the API surface of
types2.Type and to match the approach taken in go/types. The converter
methods for Named and TypeParam will be addressed in a follow-up CL.
Also: Fixed behavior of optype to return the underlying type for
arguments that are not type parameters.

Also, make some fmt changes so that the type parameters and the
typeparam type are displayed in -W=2.
You can now parse a simple generic function (but not generic calls or generic
types) and print out the noder IR via 'go tool compile -G=2 -W=2 func.go'

types2 and importer
This is a copy of the importer and types2 (unreviewed) prototype version
excluding the testdata directory containing tests (see below). Each file
is marked with the comment
// UNREVIEWED
on the first line. The plan is to check in this code wholesale (it runs and
passes all tests) and then review the code file-by-file via subsequent CLs
and remove the "// UNREVIEWED" comments as we review the files.
Since most tests are unchanged from the original go/types, the next CL will
commit those tests as they don't need to be reviewed again. (Eventually we
may want to factor them out and share them from a single place, e.g. the
test directory.)
The existing file fmtmap_test.go was updated.
