My primary concern here is that we're unconditionally iterating over every instruction in the module, even if the pass has nothing to do. In the grand scheme of things, it isn't *that* expensive, but it's still not cheap, and we seem to have grown a number of passes doing similar walks. Can we merge this with some other walk over the module?
