This is a port of CL 343933 from go/types with the necessary
adjustments in the compiler.
With this CL type parameters and type lists are now held in
TParamList and TypeList data types which don't expose the
internal representation.

type param lists
This is a port of CL 343932 from go/types, with the necessary adjustments
to the compiler.
This change improves type safety slightly, avoids many internal type
assertions, and simplifies some code paths.

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.

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.

eliminate sanitization
This is a port of CL 335929 to types2. It differs significantly from
that CL to handle lazy loading, which wasn't tested in go/types.
Additionally, the *Checker field was moved out of instance and back
onto Named. This way we can tell whether a Named type is uninstantiated
simply by checking whether Named.instance is non-nil, which simplified
the code considerably.
Fixes #46151

Changed the implementation such that the result is a variable rather than
a constant if the argument type (or the struct in case of unsafe.Offsetof)
has a size that depends on type parameters.

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).

- 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.
For #45346.

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.

This change makes a first connection between the compiler and types2.
When the -G flag is provided, the compiler accepts code using type
parameters; with this change generic code is also type-checked (but
then compilation ends).

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.
