Fix RWMutex to be thread-safe when pthread_rwlock is not available
lib/Support/RWMutex.cpp contains an implementation of RWMutex that
uses pthread_rwlock, but when pthread_rwlock is not available (such as
under NaCl, when using newlib), it silently falls back to using the
no-op definition in lib/Support/Unix/RWMutex.inc, which is not
thread-safe.
Fix this case to be thread-safe by using a normal mutex.
