Updated per review.

Checking a GlobalAddress without an explicit check for a PCREL_ BasePtr is now done instead by assuming that this will always be in the first operand of BasePtr. Not sure if this is better... Perhaps better to either assume that all GlobalAddress nodes are lowered with a PCREL_ node (call isPCRel()), or maybe check *all* operands of BasePtr for a GlobalAddress?
