The syntax for go and defer specifies an arbitrary expression, not
a call; the call requirement is spelled out in prose. Don't to the
call check in the parser; instead move it to the type checker. This
is simpler and also allows the type checker to check expressions that
are not calls, and avoid "not used" errors due to such expressions.
We would like to make the same change in go/parser and go/types
but the change requires Go/DeferStmt nodes to hold an ast.Expr
rather than an *ast.CallExpr. We cannot change that for backward-
compatibility reasons. Since we don't test this behavior for the
type checkers alone (only for the compiler), we get away with it
for now.
Follow-up on CL 425675 which introduced the extra errors in the
first place.

Shape-based stenciling in unified IR is done by converting type argument
to its underlying type. So it agressively check that type argument is
not a TFORW. However, for recursive instantiated type argument, it may
still be a TFORW when shapifying happens. Thus the assertion failed,
causing the compiler crashing.
To fix it, just allow fully instantiated type when shapifying.

In typebits.Set we check that the offset is a multiple of the
alignment, which makes perfect sense. But for values like
atomic.Int64, which has 8-byte alignment even on 32-bit platforms
(i.e. the alignment is larger than PtrSize), if it is on stack it
may be under-aligned, as the stack frame is only PtrSize aligned.
Normally we would prevent such values on stack, as the escape
analysis force values with higher alignment to heap. But for a
composite literal assignment like x = AlignedType{...}, the
compiler creates an autotmp for the RHS then copies it to the LHS.
The autotmp is on stack and may be under-aligned. Currently this
may cause an ICE in the typebits.Set check.
This CL makes it align the _offset_ of the autotmp to 8 bytes,
which satisfies the check. Note that this is actually lying: the
actual address at run time may not necessarily be 8-byte
aligned as we only align SP to 4 bytes.
The under-alignment is probably okay. The only purpose for the
autotmp is to copy the value to the LHS, and the copying code we
generate (at least currently) doesn't care the alignment beyond
stack alignment.

Normally, when moving Go values of type T from one location to another,
we don't need to worry about partial overlaps. The two Ts must either be
in disjoint (nonoverlapping) memory or in exactly the same location.
There are 2 cases where this isn't true:
1) Using unsafe you can arrange partial overlaps.
2) Since Go 1.17, you can use a cast from a slice to a ptr-to-array.
https://go.dev/ref/spec#Conversions_from_slice_to_array_pointer
This feature can be used to construct partial overlaps of array types.
var a [3]int
p := (*[2]int)(a[:])
q := (*[2]int)(a[1:])
*p = *q
We don't care about solving 1. Or at least, we haven't historically
and no one has complained.
For 2, we need to ensure that if there might be partial overlap,
then we can't use OpMove; we must use memmove instead.
(memmove handles partial overlap by copying in the correct
direction. OpMove does not.)
Note that we have to be careful here not to introduce a call when
we're marshaling arguments to a call or unmarshaling results from a call.

CL 414836 limited the check for implicit dot for method call enabled by
a type bound. However, the checking condition for ODOTMETH only is not
right. For example, for promoted method, we have a OXDOT node instead,
and we still have to check for implicit dot in this case.
However, if the base type and embedded types have the same method name,
e.g in issue #53419, typecheck.AddImplicitDots will be confused and
result in an ambigus selector.
To fix this, we ensure methods for the base type are computed, then only
do the implicit dot check if we can find a matched method.

I structured the test for issue54343.go after issue46725.go, where I
was careful to use `[4]int`, which is a type large enough to avoid the
tiny object allocator (which interferes with finalizer semantics). But
in that test, I didn't note the importance of that type, so I
mistakenly used just `int` in issue54343.go.
This CL switches issue54343.go to use `[4]int` too, and then adds
comments to both pointing out the significance of this type.

For selector expression "x.M" where "M" is a promoted method, irgen is using
the type of receiver "x" for determining the typeparams for instantiation.
However, because M is a promoted method, so its associated receiver is
not "x", but "x.T" where "T" is the embedded field of "x". That casues a
mismatch when converting non-shape types arguments.
Fixing it by using the actual receiver which has the method, instead of
using the base receiver.

As it can't appear in user package paths.
There is a hack for handling "go:buildid" and "type:*" on windows/386.
Previously, windows/386 requires underscore prefix on external symbols,
but that's only applied for SHOSTOBJ/SUNDEFEXT or cgo export symbols.
"go.buildid" is STEXT, "type.*" is STYPE, thus they are not prefixed
with underscore.
In external linking mode, the external linker can't resolve them as
external symbols. But we are lucky that they have "." in their name,
so the external linker see them as Forwarder RVA exports. See:
- https://docs.microsoft.com/en-us/windows/win32/debug/pe-format#export-address-table
- https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=ld/pe-dll.c;h=e7b82ba6ffadf74dc1b9ee71dc13d48336941e51;hb=HEAD#l972)
This CL changes "." to ":" in symbols name, so theses symbols can not be
found by external linker anymore. So a hacky way is adding the
underscore prefix for these 2 symbols. I don't have enough knowledge to
verify whether adding the underscore for all STEXT/STYPE symbols are
fine, even if it could be, that would be done in future CL.

In this test, traditionally the comparison `*l == r[0]` was left as a
comparison between `*l` (type `any`) and `r[0]` (type `*int`), and the
rest of the compiler needed to handle mixed-typed comparisons.
However, this means more complexity for wiring up explicit rtypes.
To simplify rtype handling, the next CL will change unified IR to
instead handle the expression as `*l == any(r[0])`. However, a
consequence of this currently is that walk will now sequence the
`any(r[0])` expression first, because it involves a
concrete-to-interface conversion. And in turn, this means the `r[0]`
panic ("index out of bounds") will take priority over the `*l`
panic ("nil pointer dereference").
This is a change in user-visible semantics in some cases, but the Go
spec leaves this unspecified, so it shouldn't be an issue. Note also:
gccgo has the same behavior (i.e., panicking on index out of bounds,
not nil pointer dereference), and cmd/compile also already has the
same behavior when the interface conversion is explicit (as in the
added "nil pointer dereference #3" test case).

In filenames, macOS translates Ä (U+00c4, c3 84) to Ä (U+0041 U+0308, 41 cc 88).
This causes problems for run.go's crude rules for testing the compiler.

In rare circumstances, the loaded value must be spilled because the
store can't happen yet.
In that case, we need to be able to spill the 16-byte value.

For type assertions, if either src or dst type has shape, we must
convert them to dynamic type assertions.

For constants literal, iimport/iexport read/write them as basic literal
nodes. So they are printed in diagnostic message as Go syntax. So "foo"
will be reported as string("foo").
Unified IR read/write the raw expression as string value, and when
printed in diagnostic, the string value is written out exactly as-is, so
"foo" will be written as "foo".
Thus, this CL relax the test in issue7921.go to match the string value only.

Unified IR uses to generate wrappers after the global inlining pass, so
it needs to apply inlining for the wrappers itself. However, inlining
may reveal new method value nodes which have not been seen yet, thus
unified IR never generates wrappers for them.
To fix it, just visiting the wrapper function body once more time after
inlining, and generate wrappers for any new method value nodes.
Fixes#52128
