These tests represent two patterns of usage, found in Google-internal
tests, that deadlocked after CL 506755.
TestConcurrentRun is a minor variation on TestParallelSub, with the
additional expectation that the concurrent calls to Run (without
explicit calls to Parallel) proceed without blocking. It replaces
TestParallelSub.
TestParentRun is similar, but instead of calling Run concurrently it
calls Run from within the subtest body. It almost certainly represents
an accidental misuse of T.Run, but since that pattern used to run to
completion we don't want to break it accidentally. (Perhaps it should
be diagnosed with a vet check instead?)
While we are testing concurrency, this also cleans up
TestConcurrentCleanup to use a clearer synchronization pattern.

The code generation on riscv64 will currently result in incorrect
assembly when a 32 bit integer is right shifted by an amount that
exceeds the size of the type. In particular, this occurs when an
int32 or uint32 is cast to a 64 bit type and right shifted by a
value larger than 31.
Fix this by moving the SRAW/SRLW conversion into the right shift
rules and removing the SignExt32to64/ZeroExt32to64. Add additional
rules that rewrite to SRAIW/SRLIW when the shift is less than the
size of the type, or replace/eliminate the shift when it exceeds
the size of the type.
Add SSA tests that would have caught this issue. Also add additional
codegen tests to ensure that the resulting assembly is what we
expect in these overflow cases.

The GoSyscallBegin event is a signal for both the P and the G to enter a
syscall state for the trace parser. (Ps can't have their own event
because it's too hard to model. As soon as the P enters _Psyscall it can
get stolen out of it.) But there's a window in time between when that
event is emitted and when the P enters _Psyscall where the P's status
can get emitted. In this window the tracer will emit the wrong status:
Running instead of Syscall. Really any call into the tracer could emit a
status event for the P, but in this particular case it's when running a
safepoint function that explicitly emits an event for the P's status.
The fix is straightforward. The source-of-truth on syscall status is the
G's status, so the function that emits the P's status just needs to
check the status of any G attached to it. If it's in _Gsyscall, then the
tracer should emit a Syscall status for the P if it's in _Prunning.

ReadMemStats has a few assertions it makes about the consistency of the
stats it's about to produce. Specifically, how those stats line up with
runtime-internal stats. These checks are generally useful, but crashing
just because some stats are wrong is a heavy price to pay.
For a long time this wasn't a problem, but very recently it became a
real problem. It turns out that there's real benign skew that can happen
wherein sysmon (which doesn't synchronize with a STW) generates a trace
event when tracing is enabled, and may mutate some stats while
ReadMemStats is running its checks.
Fix this by synchronizing with both sysmon and the tracer. This is a bit
heavy-handed, but better that than false positives.
Also, put the checks behind a debug mode. We want to reduce the risk of
backporting this change, and again, it's not great to crash just because
user-facing stats are off. Still, enable this debug mode during the
runtime tests so we don't lose quite as much coverage from disabling
these checks by default.

The exitsyscall path, since the introduction of the new execution
tracer, stores a just little bit more data in the exitsyscall stack
frame, causing a build failure from exceeding the nosplit limit with
'-N -l' set on all packages (like Delve does).
One of the paths through which this fails is "throw" from wirep, called
by a callee of exitsyscall. By switching to the systemstack on this
path, we can avoid hitting the nosplit limit, fixing the build. It's
also not totally unreasonable to switch to the systemstack for the
throws in this function, since the function has to be nosplit anyway. It
gives the throw path a bit more wiggle room to dump information than it
otherwise would have.

the assumption that traceThreadDestroy is getting called when the thread

dropping never leaves the allm list. Nevertheless, traceThreadDestroy
