loadiwkey and aesenc128kl share the same opcode but one is memory and one is register. But they're behavior is quite different. We were crashing because one has an output register and one doesn't and the backend couldn't account for that. But since they aren't foldable we can just add NotMemoryFoldable so they won't be looked at.
