085529bd5f cmd/compile: fix wrong unsafe.Offsetof evaluation inside generic function
For instantiated generic functions, all implicit dot operations are
resolved. Thus unsafe.Offsetof may calculating the offset against the
wrong base selector.

To fix it, we must remove any implicit dot operations to find the first
non-implicit one, which is the right base selector for calculating the
offset.

70d499cd89 test/heapsampling.go: slow down allocation rate and reduce iterations
As far as I can tell, this test suffers from #52433. For some reason,
this seems to become more of a problem on the windows/386 than anywhere
else. This CL is an attempt at a mitigation by slowing down the
allocation rate by inserting runtime.Gosched call in the inner loop. It
also cuts the iteration count which should help too (as less memory is
allocated in total), but the main motivation is to make sure the test
doesn't take too long to run.

Fixes #49564.

1f0ef6bec7 runtime: cancel mark and scavenge assists if the limiter is enabled
This change forces mark and scavenge assists to be cancelled early if
the limiter is enabled. This avoids goroutines getting stuck in really
long assists if the limiter happens to be disabled when they first come
into the assist. This can get especially bad for mark assists, which, in
dire situations, can end up "owing" the GC a really significant debt.

For #52890.

d29d0314c1 runtime: don't inspect the stack for delayed signals from TSAN
Cgo TSAN (not the Go race detector) intercepts signals and calls
the signal handler at a later time. When the signal handler is
called, the memory may have changed, but the signal context
remains old. As the signal context and the memory don't match, it
is unsafe to unwind the stack from the signal PC and SP. We have
to ignore the signal.

It is probably also not safe to do async preemption, which relies
on the signal PC, and inspects and even writes to the stack (for
call injection).

We also inspect the stack for fatal signals (e.g. SIGSEGV), but I
think they are not delayed. For other signals we don't inspect
the stack, so they are probably fine.

Fixes #27540.

f8c26a59a4 syscall: update linux/loong64 kernel ABI, emulate fstatat with statx
The linux/loong64 kernel ABI has changed a little since the inception
of the Go port; most notably fstat and fstatat are being removed [1],
leaving only statx as the stat mechanism. Fortunately the structs are
easy enough to translate, and we now exclusively use statx across the
board on loong64 for best compatibility with past and future kernels
(due to the architecture's young age, statx is always available).

In wiring up the statx calls, it turned out the linux/loong64 syscall
definitions were out-of-date, so the generation script received some
tweaking as well.

78b8e4fbce cmd/dist: support spaces and quotes in CC
As of CL 334732 `go build` can accept `$CC` with spaces and quotes,
which lets us easily use `zig cc` as the C compiler, or easily pass
extra compiler parameters:

```
CC="zig cc" go build <...>
CC="clang-13 -v" go build <...>
CC="zig cc -Wl,--print-gc-sections" go build <...>
```

However, the same does not apply for building go itself:

```
$ CC="zig cc" ./make.bash
Building Go cmd/dist using /usr/local/go. (go1.18.2 linux/amd64)
go tool dist: cannot invoke C compiler "zig cc": exec: "zig cc": executable file not found in $PATH

Go needs a system C compiler for use with cgo.
To set a C compiler, set CC=the-compiler.
To disable cgo, set CGO_ENABLED=0.
```

With this change Go can be built directly with `zig cc` (the linker arg
will disappear with CL 405414):

```
$ CC="zig cc -Wl,--no-gc-sections" ./make.bash
Building Go cmd/dist using /usr/local/go. (go1.18.2 linux/amd64)

... and this is what we are doing. Tested with zig
0.10.0-dev.2252+a4369918b

This is a continuation of CL 405414: the original one broke AIX and iOS
builds. To fix that, added `unknown option` to the list of strings
under lookup.

d5ae7a6487 go/types, types2: remove redundant calls to Named.resolve
The resolved status of a Named type should be owned by its API, and
callers should access resolved data via methods. Remove several
instances where Named.resolve is explicitly invoked, only to be followed
by a method that also resolves.

Also make two minor cleanups:
- Remove the tparams parameter to Checker.newNamed, as it was unused.
- Include position information when assertions fail, so that one doesn't
  need to go digging in the panicking stack to find the assertion
  location.

7ce3864156 cmd/go/internal/modfetch: wrap errors from HTTP response bodies
The Read method on the Body returned from a net/http.Transport does
not wrap errors returned by the underlying io.Reader and returns a
bare io.ErrUnexpectedEOF if the body is shorter than the declared
Content-Length.

Since we can't feasibly add detail on the net/http side without
breaking established users, we must instead add detail on the caller
side. Since the net/http client uses url.Error for most of its own
errors, we use that same error type here.

I have not added a regression test for this change. (While it is
theoretically possible to set up a GOPROXY that returns incorrect
Content-Length headers, the change seems straightforward enough that
it isn't worth the complex test setup.)

70668a4144 go/types, types2: don't panic with invalid recursive generic type
Add cycle detection to hasVarType to avoid infinite recursions
caused by invalid cyclic types. This catches cases where the
validType check has not yet run or has checked differently
instantiated types.

As an alternative, validType could mark invalid *Named types
by setting their underlying types to Typ[Invalid]. That does
work but discards information which leads to undesired effects
with other errors. A better mechanism might be to explicitly
track in *Named if a type is invalid and why it is invalid,
and connect that with a general validity attribute on types.
That's a more invasive change we might consider down the road.

Fixes #52915.

2138124143 go/types, types2: detect dupl. map keys in comp. literals with generic key type
For map composite literals where the key type is a suitably constrained
type parameter, the existing key duplicate detection mechanism doesn't
work when the keys are numeric values of different types but equal value.
For instance, given

        func _[P int64|float64]() {
                _ = map[P]string{0: "foo", 0.0: "bar"}
        }

the key values 0 and 0.0 have the same numeric value 0 but currently
are treated as different values int64(0) and float64(0.0). For any
valid instantiation of P, the keys will collide.

This CL changes the keyVal function to map numeric types to the
"smallest" numeric type in which a value can be represented. For
instance, float64(0.0) is mapped to int64(0). This ensures that
numerically equal values are always represented the same way so
that they can be detected as duplicates.

Fixes #51610.
