[analyzer] Add dispatch_data_create as a special case in RetainCountChecker.
This function receives a callback block. The analyzer suspects that this block
may be used to take care of releasing the libdispatch object returned from
the function. In fact, it doesn't - it only releases the raw data buffer.
Inform the analyzer about that. Fixes the resulting false negatives.
