55b8e16b2e testing: use monotonic counts to attribute races in subtests
This implements the approach I described in
https://go-review.git.corp.google.com/c/go/+/494057/1#message-5c9773bded2f89b4058848cb036b860aa6716de3.

Specifically:

- Each level of test atomically records the cumulative number of races
  seen as of the last race-induced test failure.

- When a subtest fails, it logs the race error, and then updates its
  parents' counters so that they will not log the same error.

- We check each test or benchmark for races before it starts running
  each of its subtests or sub-benchmark, before unblocking parallel
  subtests, and after running any cleanup functions.

With this implementation, it should be the case that every test that
is running when a race is detected reports that race, and any race
reported for a subtest is not redundantly reported for its parent.

The regression tests are based on those added in CL 494057 and
CL 501895, with a few additions based on my own review of the code.

Fixes #60083.

9cdcb01320 runtime/pprof: include labels for caller of goroutine profile
The goroutine profile has close to three code paths for adding a
goroutine record to the goroutine profile: one for the goroutine that
requested the profile, one for every other goroutine, plus some special
handling for the finalizer goroutine. The first of those captured the
goroutine stack, but neglected to include that goroutine's labels.

Update the tests to check for the inclusion of labels for all three
types of goroutines, and include labels for the creator of the goroutine
profile.

e46e8610ab crypto/internal/boring: use noescape and nocallback cgo directives
The new noescape and nocallback directives can be used instead of the C
wrapper functions that are there just to avoid some parameters being
escaped to the heap.

This CL also helps demonstrate the use of the new directives in real
code.

I've added some benchmarks to demonstrate that this CL doesn't
introduce new heap allocations when using boringcrypto:

255ed03a94 runtime: allow for 10 more threads in TestWindowsStackMemory*
CL 473415 allowed 5 more threads in TestWindowsStackMemory, to cover
sysmon and any new threads in future. However, during go1.22 dev cycle,
the test becomes flaky again, failing in windows-386 builder a couple of
times in CL 535975 and CL 536175 (and maybe others that haven't caught).

This CL increases the extra threads from 5 to 10, hopefully to make the
test stable again for windows-386. The theory is that Go process load a
bunch of DLLs, which may start their own threads. We could investigate
more deeply if the test still be flaky with 10 extra threads.

Fixes #58570

It's definition, in cryptbase.dll, is an opaque wrapper for the
documented API ProcessPrng. Instead of using RtlGenRandom, switch to
using ProcessPrng, since the former is simply a wrapper for the latter,
there should be no practical change on the user side, other than a minor
change in the DLLs we load.

3754ca0af2 cmd/compile: improve the implementation of Lowered{Move,Zero} on linux/loong64
Like the CL 487295, when implementing Lowered{Move,Zero}, 8 is first subtracted
from Rarg0 (parameter Ptr), and then the offset of 8 is added during subsequent
operations on Rarg0. This operation is meaningless, so delete it.

Change LoweredMove's Rarg0 register to R20, consistent with duffcopy.

4c31dfe850 cmd/go: introduce Shell abstraction
This CL separates running shell commands and doing shell-like
operations out of the Builder type and into their own, new Shell type.
Shell is responsible for tracking output streams and the Action that's
running commands. Shells form a tree somewhat like Context, where new
Shells can be derived from a root shell to adjust their state.

The primary intent is to support "go build -json", where we need to
flow the current package ID down to the lowest level of command output
printing. Shell gives us a way to easily flow that context down.

However, this also puts a clear boundary around how we run commands,
removing this from the rather large Builder abstraction.

For #62067.

eabf3bf688 cmd/go: serialize access to scriptDir with output
Currently, Builder.fmtcmd can read scriptDir without taking the output
lock. This introduces a potential data race between the read in fmtcmd
and the write in Showcmd. There's also a logical race here: because
fmtcmd doesn't know when its output is going to be printed, Showcmd
may print a "cd" command between when fmtcmd is called and when its
output is printed. As a result, it doesn't make sense to just lock
around the access in fmtcmd.

Instead, move the entire scriptDir substitution to Showcmd. This will
generally result in the same output. In the cases where Builder.run is
called with a non-empty desc, it means we may print a full path in the
comment line above output rather than substituting the script
directory. I think this is okay.

This lets us undo the workaround in CL 536355.

ab5bd15941 cmd/go: clean up adding import path to command error
Currently, cmdError makes a somewhat fuzzy attempt to ensure the
package import path is part of the printed error, using a string
prefix check. Also, if it decides it does need to add the import path,
it prints it as a "go build" line, which could be misleading because
it can happen outside of "go build".

Clean up the whole code path by explicitly checking the provided error
description against Package.Desc(), and instead of emitting "go build"
in the error message, print it as "# importPath" just like we do in
the common case.

3803c85880 cmd/go: work around race in fmtCmd
CL 529219 made an existing race with accessing Builder.scriptDir from
Builder.fmtcmd (and now also Builder.Showcmd) much more likely by
dropping a theoretically unnecessary condition from the call from
Builder.run to Builder.fmtcmd.

For an example race report, see
https://build.golang.org/log/c3cad62d0fc33a8381d2091661c685ea1fc525c4

The race is between

  (*Builder).cover2() -> (*Builder).run() -> (*Builder).fmtcmd()

and various other call paths of the form

  (*Builder).build() -> (*gcToolchain).*  (*Builder).Showcmd() -> (*Builder).fmtcmd()

The race can be reproduced with

  go install -race cmd/go
  stress -p 1 go test -x -cover -a log

Return this race to its existing likelihood by putting the condition
back. This isn't a "correct" solution because the race could still
happen if the "cover" tool invoked by Builder.cover2 emits output. But
this will do for a temporary fix.
