Sergey Matveev 14b9924c7b Clean up StopTheWorld code after r192686.
Remove outdated comments. Also remove code that handled an issue in libc's
sigaction(), which we don't use anymore.

Sergey Matveev 6f7fb43ad3 [sanitizer] Fix the parent liveness check in StopTheWorld.
Comparing the parent PID with 1 isn't sufficient to ensure the parent is alive,
because of prctl(PR_SET_CHILD_SUBREAPER, ...). Compare with the real parent's
recorded PID instead.

Sergey Matveev adef754297 [sanitizer] Fix deadlock in StopTheWorld.
The tracer thread in StopTheWorld could wait on a mutex forever if the parent
process died before unlocking it. Use PR_SET_PDEATHSIG so that the parent would
kill the child in this scenario.

Sergey Matveev 69931c5841 [sanitizer_common] Add internal_clone().
Add a wrapper for the clone syscall for use in StopTheWorld. We
implement it only for x86_64, so stop building StopTheWorld for other platforms
(no one uses it outside x86_64 anyway).

See https://code.google.com/p/address-sanitizer/issues/detail?id=214 for why we
can't use the glibc clone() wrapper.

Sergey Matveev ef7db73e11 [sanitizer] Handle Die() in StopTheWorld.
Handle calls to Die() from the tracer thread. Fixes a bug where a CHECK
could fail in the tracer thread, resulting in a call to AsanDie. The tracer
thread then exited and the parent process continued execution despite its
address space being in an unusable state.
