tsan: Adding releaseAcquire() to ThreadClock

realeaseAcquire() is a new function added to TSan in support of the Go data-race detector.
It's semantics is:

void ThreadClock::releaseAcquire(SyncClock *sc) const {
  for (int i = 0; i < kMaxThreads; i++) {
    tmp = clock[i];
    clock[i] = max(clock[i], sc->clock[i]);
    sc->clock[i] = tmp;
  }
}

tsan: allow the Go runtime to return multiple stack frames for a single PC

This fix allows tsan to report stack traces correctly even in the
presence of mid-stack inlining by the Go compiler.

See https://go-review.googlesource.com/c/go/+/195781 for the Go runtime side of this change.
