Kuba Mracek faef7d034a [tsan] Avoid calling Block_copy in the "sync" GCD interceptors ...

The synchronous dispatch functions in GCD (dispatch_sync, dispatch_barrier_sync), don't make a copy of the passed block. To maintain binary compatibility, we should avoid doing that as well in TSan, as there's no reason to do that. The synchronous dispatch functions will not return before the block is actually executed.
