  Changed paths:
    M llvm/utils/remote-exec.py

  Log Message:
  -----------
  remote-exec: Detect and propagate signal death in the remote process.

If the remote process died with a signal, this will be exposed by ssh
as an exit code in the range 128 < rc < 160. We may be running under
`not --crash` which will expect us to also die with a signal, so send
the signal to ourselves so that wait4() in `not` will detect the signal.

Speculative fix for failing buildbot:
