User errors should be reported in noder and/or typecheck, we already
know the -lang flag's value during noding, and checking it then works
better for unified IR.
The "multiple files for type" and "cannot apply to var of type" errors
should also be moved to typecheck, but then they'd have to be
duplicated for -G=3 mode (because it avoids typecheck). So those are
left behind for now.

When ABI wrappers are used, there are cases where in Go code we
need the PC of the defined function instead of the ABI wrapper.
Currently we work around this by define such functions as
ABIInternal, even if they do not actually follow the internal ABI.
This CL introduces internal/abi.FuncPCABIxxx functions as compiler
intrinsics, which return the underlying defined function's entry
PC if the argument is a direct reference of a function of the
expected ABI, and reject it if it is of a different ABI.
As a proof of concept, change runtime.goexit back to ABI0 and use
internal/abi.FuncPCABI0 to retrieve its PC.
Updates #44065.

The go/build package needs access to this configuration,
so move it into a new package available to the standard library.

This CL restructures how we track function ABIs and generate ABI
wrappers in the compiler and adds import/export of ABIs across package
boundaries.
Currently, we start by tracking definition and referencing ABIs in two
global maps and eventually move some of this information into the
LSyms for functions. This complicates a lot of the existing code for
handling wrappers and makes it particularly hard to export ABI
information across packages. This change is built around instead
recording this information on the ir.Func.
First, this change replaces the global ABI def/ref maps with a type,
which makes the data flow and lifetime of this information clear in
gc.Main. These are populated during flag parsing.
Then, early in the front-end, we loop over all ir.Funcs to 1. attach
ABI def/ref information to the ir.Funcs and 2. create new ir.Funcs for
ABI wrappers. Step 1 is slightly subtle because the information is
keyed by linker symbol names, so we can't simply look things up in the
compiler's regular symbol table.
By generating ABI wrappers early in the front-end, we decouple this
step from LSym creation, which makes LSym creation much simpler (like
it was before ABI wrappers). In particular, LSyms for wrappers are now
created at the same time as all other functions instead of by
makeABIWrapper, which means we're back to the simpler, old situation
where InitLSym was the only thing responsible for constructing
function LSyms. Hence, we can restore the check that InitLSym is
called exactly once per function.
Attaching the ABI information to the ir.Func has several follow-on
benefits:
1. It's now easy to include in the export info. This enables direct
cross-package cross-ABI calls, which are important for the performance
of calling various hot assembly functions (e.g., internal/bytealg.*).
This was really the point of this whole change.
2. Since all Funcs, including wrappers, now record their definition
ABI, callTargetLSym no longer needs to distinguish wrappers from
non-wrappers, so it's now nearly trivial (it would be completely
trivial except that it has to work around a handful of cases where
ir.Name.Func is nil).
The simplification of callTargetLSym has one desirable but potentially
surprising side-effect: the compiler will now generate direct calls to
the definition ABI even when ABI wrappers are turned off. This is
almost completely unnoticeable except that cmd/internal/obj/wasm looks
for the call from runtime.deferreturn (defined in Go) to
runtime.jmpdefer (defined in assembly) to compile is specially. That
now looks like a direct call to ABI0 rather than going through the
ABIInternal alias.
While we're in here, we also set up the structures to support more
than just ABI0 and ABIInternal and add various additional consistency
checks all around.
Performance-wise, this reduces the overhead induced by wrappers from
1.24% geomean (on Sweet) to 0.52% geomean, and reduces the number of
benchmarks impacts >2% from 5 to 3. It has no impact on compiler speed.

Function values must always point to the ABIInternal entry point of a
function. It wasn't entirely obvious to me we were getting this right,
so this CL adds checks for this.

This is a cleanup to bring funcsym tracking a little closer to the
ir.Func. (I thought I needed this for a later change. That turned out
not to be the case, but it's a nice cleanup.)

This merge had two conflicts to resolve:
1. The embed code on master had somewhat substantially diverged, so
this CL tediously backported the changes to dev.regabi. In particular,
I went through all of the embed changes to gc/{embed,noder,syntax}.go
and made sure the analogous code on dev.regabi in noder/noder.go and
staticdata/embed.go mirrors it.
2. The init-cycle reporting code on master was extended slightly to
track already visited declarations to avoid exponential behavior. The
same fix is applied on dev.regabi, just using ir.NameSet instead of
map[ir.Node]bool.

Currently there's a lot of logic within package types for creating
Linksyms. This CL pulls it out into base, where it can be more easily
reused by other compiler code that shouldn't need to depend on package
types.
Package base probably isn't the best place for this, but it's
convenient because it's a package that types already depends on. It's
also where the Ctxt object lives, which these functions depend upon.
Passes toolstash -cmp w/ -gcflags=all=-abiwrap.

functions
Those functions only use (*ir.Name).Linksym(), so just change them to
get an *obj.LSym directly. This helps get rid of un-necessary
validations that their callers have already done.

recent renames
Went in a semi-automated way through the clearest renames of functions,

InitLSym is where we're now generating ABI wrappers, so it seems as
good a place as any to make sure we're generating the degenerate
closure wrappers for declared functions and methods.

This largely gets rid of the remaining direct Linksym calls, hopefully
enough to discourage people from following bad existing practice until
Sym.Linksym can be removed entirely.

Syms are meant to be just interned (pkg, name) tuples, and are a
purely abstract, Go-language concept. As such, associating them with
linker symbols (a low-level, implementation-oriented detail) is
inappropriate.
There's still work to be done before linker symbols can be directly
attached to their appropriate, higher-level objects instead. But in
the mean-time, we can at least add helper functions and discourage
folks from using Sym.Linksym directly. The next CL will mechanically
rewrite code to use these helpers where possible.
Passes toolstash -cmp.
