[PATCH] D14288: [tsan] Alternative ThreadState storage for OS X

Updating patch to implement async-signal-safety.

I'm unsure about the destruction of ThreadState in cur_thread_finalize, does that need to be signal aware as well?  But that only happens once in a thread, and it seems it's already too late for a signal handler to do anything reasonable, and we don't want it to resurrect the ThreadState.  What is the behavior on Linux with regular __thread ThreadState?
