Shaohua Wang f59d68eeae BUG#21102971 data corruption on arm64
The root cause is that x86 has a stronger memory model than the ARM
processors. And the GCC builtins didn't issue the correct fences when
setting/unsetting the lock word. In particular during the mutex release.

The solution is rewriting atomic TAS operations: replace '__sync_' by
'__atomic_' if possible.
