Dimitry Andric 1c21bfb1b1 Apply fix for ThreadSanitizer false positive data race reports
Merge commit 28fb22c90fe7 from llvm git (by Dimitry Andric):

  [TSan] Handle FreeBSD specific indirection of libpthread functions

  Similar to 60cc1d3218fc for NetBSD, add aliases and interceptors for the
  following pthread related functions:

  - pthread_cond_init(3)
  - pthread_cond_destroy(3)
  - pthread_cond_signal(3)
  - pthread_cond_broadcast(3)
  - pthread_cond_wait(3)
  - pthread_mutex_init(3)
  - pthread_mutex_destroy(3)
  - pthread_mutex_lock(3)
  - pthread_mutex_trylock(3)
  - pthread_mutex_unlock(3)
  - pthread_rwlock_init(3)
  - pthread_rwlock_destroy(3)
  - pthread_rwlock_rdlock(3)
  - pthread_rwlock_tryrdlock(3)
  - pthread_rwlock_wrlock(3)
  - pthread_rwlock_trywrlock(3)
  - pthread_rwlock_unlock(3)
  - pthread_once(3)
  - pthread_sigmask(3)

  In FreeBSD's libc, a number of internal aliases of the pthread functions
  are invoked, typically with an additional prefixed underscore, e.g.
  _pthread_cond_init() and so on.

  ThreadSanitizer needs to intercept these aliases too, otherwise some
  false positive reports about data races might be produced.
