I believe we shouldn't allow to look at other instructions. I am guessing we need to do that to perform combines at legalization time and I think we shouldn't go in that direction. I would rather have the combines be a separate pass. I.e., we are not taking the same approach as SelectionDAG here.

Aditya, is this really needed to perform legalization?
