    M compiler-rt/test/tsan/signal_thread2.cpp

  Log Message:
  -----------
  [compiler-rt] Also consider SIGPROF as a synchronous signal

Blocking that signal causes inter-blocking for profilers that monitor
threads through that signal.

Update tests accordingly to use an uncaught signal.

This is a recommit of 6f3f659ce9ab91002b4a490b0ce4b085981383cd with the
tests fixed.

Fix #83844 and #83561
