The latest version of Wasmtime, 14.0.4 as of writing this, offers a new
CLI while also supporting the old CLI. Since this is known and tracked
in issue #63718, silence the warning that otherwise causes many tests
to fail.
Since Wasmtime 13 and older don't pay attention to WASMTIME_NEW_CLI,
this change increases compatibility of the script, letting it work
with Wasmtime 9.0.1 as currently tested by the old cmd/coordinator, and
with Wasmtime 14.0.4 as currently tested in the new LUCI infrastructure.
The rest of the transition is left as future work.

Tests in rlimit_test.go exist to test the behavior of automatically
bumping RLIMIT_NOFILE on Unix implemented in rlimit.go (issue #46279),
with darwin-specific behavior split out into rlimit_darwin.go and
the rest left empty in rlimit_stub.go.
Since the behavior happens only on Unix, it doesn't make sense to test
it on other platforms. Copy rlimit.go's 'unix' build constraint to
rlimit_test.go to accomplish that.
Also simplify the build constraint in rlimit_stub.go while here,
so that its maintenance is easier and it starts to match all
non-darwin Unix GOOS values (previously, 'hurd' happened to be missed).
In particular, this fixes a problem where TestOpenFileLimit was
failing in some environments when testing the wasip1/wasm port.
The RLIMIT_NOFILE bumping behavior isn't implemented there, so
the test was testing the environment and not the Go project.
Updates #46279.

When selecting the hottest edge to use for PGO-based devirtualization,
edges are order by:
1. Edge weight
2. If weights are equal, prefer the edge with IR available in the
package.
3. Otherwise, simply sort lexicographically.
The existing logic for (2) is incomplete.
If the hottest edge so far is missing IR, but the new edge has IR, then
it works as expected and selects the new edge.
But if the hottest edge so far has IR and the new edge is missing IR, we
want to always keep the hottest edge so far, but this logic will fall
through and use lexicographical ordering instead.
Adjust the check to always make an explicit choice when IR availability
differs.

Since CL 226138, TestNohup has a bit of a strange construction: it wants
to run the "uncaught" subtests in parallel with each other, and the
"nohup" subtests in parallel with each other, but also needs join
between "uncaught" and "nohop" so it can Stop notifying for SIGHUP.
It achieves this by doing `go t.Run` with a WaitGroup rather than using
`t.Parallel` in the subtest (which would make `t.Run` return immediately).
However, this makes things more difficult to understand than necessary.
As noted on https://pkg.go.dev/testing#hdr-Subtests_and_Sub_benchmarks,
a second layer of subtest can be used to join parallel subtests.
Switch to this form, which makes the test simpler to follow
(particularly the cleanup that goes with "uncaught").

Prior to CL 460595, Lstat reported most reparse points as regular
files. However, reparse points can in general implement unusual
behaviors (consider IO_REPARSE_TAG_AF_UNIX or IO_REPARSE_TAG_LX_CHR),
and Windows allows arbitrary user-defined reparse points, so in
general we must not assume that an unrecognized reparse tag represents
a regular file; in CL 460595, we began marking them as irregular.
As it turns out, the Data Deduplication service on Windows Server runs
an Optimization job that turns regular files into reparse files with
the tag IO_REPARSE_TAG_DEDUP. Those files still behave more-or-less
like regular files, in that they have well-defined sizes and support
random-access reads and writes, so most programs can treat them as
regular files without difficulty. However, they are still reparse
files: as a result, on servers with the Data Deduplication service
enabled, files could arbitrarily change from “regular” to “irregular”
without explicit user intervention.
Since dedup files are converted in the background and otherwise behave
like regular files, this change adds a special case to report DEDUP
reparse points as regular.
Fixes#63429.
No test because to my knowledge we don't have any Windows builders
that have the deduplication service enabled, nor do we have a way to
reliably guarantee the existence of an IO_REPARSE_TAG_DEDUP file.
(In theory we could add a builder with the service enabled on a
specific volume, write a test that encodes knowledge of that volume,
and use the GO_BUILDER_NAME environment variable to run that test only
on the specially-configured builders. However, I don't currently have
the bandwidth to reconfigure the builders in this way, and given the
simplicity of the change I think it is unlikely to regress
accidentally.)

When parsing a declaration of the form
type a [b[c]]d
where a, b, c, d stand for identifiers, b[c] is parsed as a type
constraint (because an array length must be constant and an index
expression b[c] is never constant, even if b is a constant string
and c a constant index - this is crucial for disambiguation of the
various possibilities).
As a result, the error message referred to a missing type parameter
name and not an invalid array declaration.
Recognize this special case and report both possibilities (because
we can't be sure without type information) with the new error:
"missing type parameter name or invalid array length"
ALso, change the previous error message
"type parameter must be named"
to
"missing type parameter name"
which is more fitting as the error refers to an absent type parameter

On some platforms (notably OpenBSD), stacks must be specifically allocated
and marked as being stack memory. Allocate the crash stack using stackalloc,
which ensures these requirements are met, rather than using a global Go
variable.

We do the same elsewhere (e.g. in parser.name when a name is missing).
This ensures functions have a (dummy) name and a non-nil type.
Avoids a crash in the type-checker (verified manually).
A test was added here (rather than the type checker) because type-
checker tests are shared between types2 and go/types and error
recovery in this case is different.
Fixes#63835.

This change brings the error message for this case back in line
with the pre-Go1.18 error message.
