This revision now requires changes to proceed.

The issue with this change is that there is a lot of unnecessary work done now. Before, we could exit early to decide an instruction could never be hoisted/sunk. Now, we're removing all those early checks and only when actually trying to move get the "actually, you can't". I expect this to get a big compile-time penalty.
Could you do some testing and include results in the patch summary?
