Dimitry Andric 28fb22c90f [TSan] Handle FreeBSD specific indirection of libpthread functions 
Similar to 60cc1d3218 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.
