This is split off from D79799 - where I was proposing to fully iterate over a function until there are no more transforms. I suspect we are still going to want to do something like that eventually. But we can achieve the same gains much more efficiently on the current set of regression tests just by reversing the order that we visit the instructions. This may also reduce the motivation for D79078, but we are still not getting the optimal pattern for a reduction.
