As of recent changes there are now two uses for this opcode: 1. For BoundsChecking memory as before, in which case the pinned register is set. 2. For Signaling memory accesses which exceed the redzone size. I believe CSE code can handle both cases, but should avoid mixing 1. and 2. (which can't happen right now because memory is only ever one type, and we don't support multiple memories).
