Given that I wonder if it makes sense to use this pass at O1 <https://reviews.llvm.org/owners/package/1/> or O2 <https://reviews.llvm.org/owners/package/2/> and save the mostly costly analysis for O3 <https://reviews.llvm.org/owners/package/3/>.

I have seen some build systems use `-O2` for release builds. So if we go this route, maybe we could have unoptimized for `-O0` and `-O1`, and optimized for `-O2` and `-O3`.
