Kostya Serebryany a0eb97a50b [sanitizer] allow to store the lock context (stack trace id) with all currently held locks in a thread. This will allow the deadlock detector to provide better warnings (more changes to go)

Dmitry Vyukov 3b37e8bf18 tsan: yet another attempt to fix pthread_cond interceptors 
Make behavior introduced in r202820 conditional (under legacy_pthread_cond flag).
The new issue that we've hit with the satellite pthread_cond_t struct is
that pthread_condattr_getpshared does not work (satellite data is not shared between processes).
The idea is that most processes do not use pthread 2.2.5.
The rare ones that use (2.2.5 is dated by 2002) must specify legacy_pthread_cond=1
on their own risk.

Justin Bogner 8b77f351a8 Revert "profile: Use a simple binary format for profiling" 
This will break without the corresponding change in clang, which I've
reverted until I figure out how to get it to link properly.

This reverts commit r203710.

Dmitry Vyukov 8c0f86e307 tsan: fix handling of pthread_cond_wait in presence of pthread_cancel
