cmd/compile: delay fillinMethods to deal with mutually-recursive types
...
We need to delay fillinMethods until we get to a top-level type, so we
know all the TFORW types have been filled in, and we can do the
substitutions required by fillinMethods.

cmd/compile: remove ssagen/pgen_test.go
...
This test was written in 2015, and hasn't had any meaningful changes
to it since. However, it's very ad hoc and pokes into internals that
it shouldn't, and it keeps getting in the way of more meaningful
refactorings. It doesn't even catch bugs; e.g., it didn't catch that
cmpstackvarlt wasn't asymmetric (CL 19778), and a bunch of its test
cases are bogus because we never actually use it to sort ir.PFUNC
nodes (assert added in this CL).
The compiler is woefully lacking in unit tests like these, but I
strongly feel this test is more of a hinderance than a help at the
moment.

cmd/compile: move types init code into package types
...
This moves the package types setup code from package typecheck into
package types itself. This is a prereq for making types.Type more
opaque, because some unit tests depend on being able to init the basic
universal types.
A few notable details of this CL:
1. Creating the builtin types requires being able to create the
ir.Name/ir.OTYPE that represents it, but package types can't depend on
package ir. So we add a callback function to handle creating the
ir.Name.
2. This CL moves ir.Pkgs.Unsafe to types.UnsafePkg. Package unsafe is
part of the language, not like the other ir.Pkgs packages that are
purely implementation details.
3. This CL also moves typecheck.FakeRecv to types.FakeRecv, addressing
an outstanding TODO.

cmd/compile: fix reference to generic type needed by crawler
...
This problem happens when you create a new local type that uses an
imported generic type (maybe just by instantiating it), and then that
local type needed to be included as part of an export. In that case, the
imported generic type is does not have a declaration in the local
package, so it is not necessarily created in types1, so the
crawler/export doesn't work.
To fix this issue, we just need to add a call to g.obj() for the base
generic type, to make sure that it will exist if needed later in the
compilation or for the crawler during export.
Fixes #47514

We could use a syntax.Pos (no pointer) and rely on the fact
that we have a known position (or fake position, if need be)
to indicate lazy instantiation. But using a pointer leads to
a smaller Named struct.

cmd/compile: always accept 1.18 syntax but complain if not 1.18
...
This CL configures the parser to always accept 1.18 syntax
(type parameters, type instantiations, interface elements),
even when -lang is set to an earlier release.
Instead, the type checker looks for 1.18 operations and
complains if the language version is set to an earlier
release.
Doing these checks during type checking is necessary because it
it is possible to write "generic" code using pre-1.18 syntax;
for instance, an imported generic function may be implicitly
instantiated (as in imported.Max(2, 3)), or an imported constraint
interface may be embedded in an "ordinary" interface.
Fixes #47818 .

bytes, strings: optimize Trim for single byte cutsets
...
Using the latest version of all modules known by the module proxy,
we determine that for all Trim usages (and related functionality):
* 76.6% have cutsets of len=1, and
* 13.4% have cutsets of len=2.
Given that a vast majority of usages only have a cutset of len=1,
we should more heavily optimize for that situation.
Previously, there was some optimization for cutsets of len=1,
but it's within the internal makeCutsetFunc function.
This is sub-optimal as it incurs an allocation in makeCutsetFunc
for the closure over that single byte.
This CL removes special-casing of one-byte cutsets from makeCutsetFunc
and instead distributes it directly in Trim, TrimRight, and TrimLeft.
Whether we should distribute the entire ASCII cutset logic into Trim
is a future CL that should be discussed and handled separately.
The evidence for multibyte cutsets is not as obviously compelling.

[dev.cmdgo] cmd/go: fix calls to modFileGoVersion to pass in modFile
...
Before this change, we were arbitrarily picking a module to get the Go
version from in calls to modFileGoVersion. We now pass in the modFile to
modFileGoVersion when we have the file. Most of the calls were to get
the goVersion argument for commitRequirements, so now we have
commitRequirements call modFileGoVersion on the modFile directly
One of the calls to commitRequirements (when running go mod tidy with
a different Go version) passed in a new go version to update the file
to. Now, the modFile is updated before calling commitRequirements.
For the remaining cases of modFileGoVersion, it's replaced by a call to
the new (*MainModuleSet).GoVersion function, which either returns the go
version on the workspace file (in workspace mode) or the version of the
single go.mod file.

cmd/compile: fix CheckSize() calculation for -G=3 and stencils
...
Because the Align/Width of pointer types are always set when created,
CalcSize() never descends past a pointer. Therefore, we need to do
CheckSize() at every level when creating type. We need to do this for
types creates by types2-to-types1 conversion and also by type
substitution (mostly for stenciling). We also need to do
Defer/ResumeCheckSize() at the top level in each of these cases to deal
with potentially recursive types.
These changes fix issue #47929 and also allow us to remove the
special-case CheckSize() call that causes the problem for issue #47901 .

CL 37664 implemented this functionality, yet the tests were skipped.
Introduce and use additional variable groupListImplemented to
distinguish between these cases and enable TestLookupGroup for
supported configurations (which looks like all but plan9).

cmd/compile: fix checkptr false positive for (*[Big]T)(ptr)[:n:n] pattern
...
The checkptr instrumentation is currently inserted before slice
operation has validated that n <= Big. So instead of panic, checkptr
have false positive throws.
To fix this, just insert the checkptr instrumentation after the bound
checking during SSA generation.

The existing methods return new Values.
Constructing these new Values often requires allocating.
These methods allow the caller to bring their own storage.
The naming is somewhat unfortunate, in that the spec
uses the word "element" instead of "value",
as do the reflect.Type methods.
In a vacuum, MapIter.SetElem would be preferable.
However, matching the existing methods is more important.

OIDATA(OCONVIFACE(x)), there should be no OCONVIFACE operations that

cmd/compile: fix naming of types inside instantiations
...
Issues 47713 and 47877 were both due to problems with the names used for
instantiated functions/methods, which must be in sync with the names
used by types2.
- Switched to using NameString() for writing out type arguments in
instantiation names. This ensures that we are always adding the
package to type names even for the local package. Previously, we were
explicitly adding the package name for local packages, but that
doesn't handle the case when the local type is embedded inside a
pointer or slice type. By switching to NameString(), we fix #47713 .
- types1 and types2 write out 'interface {' differently (vs.
'interface{') and we were already handling that. But we needed to add
similar code to handle 'struct {' vs 'struct{'. This fixes issue
#47877 .
While fixing these bugs, I also moved some duplicated code (which
include some of the changes above) into a common function addTargs(). I
also moved InstType() name to subr.go, and renamed: MakeInstName ->
MakeFuncInstSym and MakeDictName -> MakeDictSym.
Also removed a couple of ".inst..inst." prefix checks which are
irrelvant now, since we don't add ".inst." anymore to function
instantiations.

cmd/compile: change irgen to generate exprs/stmts after decls processed
...
This CL changes irgen to wait until all top-level declarations have
been processed before constructing any expressions or statements that
reference them. This is the same approach that typecheck used.
Mechanically, it splits varDecl and funcDecl (the two top-level
declarations that can generate/contain code) into a part that runs
immediately for constructing the ir.ONAME, and then a separate task
that runs later to handle the code.
It also adds an exprStmtOK flag to indicate when it's actually safe to
start constructing (non-trivial) expressions and statements.
Fixes #47928 .
