Summary B3 / Air on ARM64: use ZR register more

B3 and Air don't really know about the ZR register. In #174818 I add storeZero64 which complements storeZero32, but really these are both hacks. The right way to do this is to add a new ImmZero operand, and add overloads on ARM64 to AirOpcode.opcodes. This is tricky to do because ARM64 means either SP or ZR depending on the instruction. That's why just doing store is so easy and hack, but kinda silly.
