Two fixes for Objetive-C methods that return struct

types.  First, I added handling for the memset intrinsic
in the IR, which is used to zero out the returned struct.
Second, I fixed the object-checking instrumentation
to objc_msgSend_stret, and generally tightened up how
the object-checking functions get inserted.
