Have you talked to anyone about the design for this?

I know Daniel Jasper, Quentin, and several others have looked at similar things before. Previous attempts have focused on using MachineLICM to do sinking as well as hoisting. While I don't have a strong opinion about one design over the other, we should be consistent about the plan here, and possibly consolidate some of the logic.
