Summary: This is done by first adding two additional instructions to convert the alloca returned address to local and convert it back to generic. Then replace all uses of alloca instruction with the converted generic address. Then we can rely NVPTXFavorNonGenericAddrSpace pass to combine the generic addresscast and the corresponding Load, Store, Bitcast, GEP Instruction together.
