[tsan] Fix synchronization in dispatch_sync
In the interceptor for dispatch_sync, we're currently missing synchronization between the callback and the code *after* the call to dispatch_sync. This patch fixes this by adding an extra release+acquire pair to dispatch_sync() and similar APIs. Added a testcase.
