libstdc++: Tweak TSan annotations for std::atomic<shared_ptr<T>>
Do not use the __tsan_mutex_not_static flag for annotation functions
where it's not a valid flag. Also use the try_lock and try_lock_failed
flags to more precisely annotate the CAS loop used to acquire a lock.
libstdc++-v3/ChangeLog:
* include/bits/shared_ptr_atomic.h (_GLIBCXX_TSAN_MUTEX_PRE_LOCK):
Replace with ...
(_GLIBCXX_TSAN_MUTEX_TRY_LOCK): ... this, add try_lock flag.
(_GLIBCXX_TSAN_MUTEX_TRY_LOCK_FAILED): New macro using
try_lock_failed flag
(_GLIBCXX_TSAN_MUTEX_POST_LOCK): Rename to ...
(_GLIBCXX_TSAN_MUTEX_LOCKED): ... this.
(_GLIBCXX_TSAN_MUTEX_PRE_UNLOCK): Remove invalid flag.
(_GLIBCXX_TSAN_MUTEX_POST_UNLOCK): Remove invalid flag.
(_Sp_atomic::_Atomic_count::lock): Use new macros.
