Personally, I would much rather teach Clang to not emit code than run a pass at O0. I really would like to preserve the ability to use O0 to understand why LLVM is misbehaving.

(The fact that we need to run the always inliner at O0 is already somewhat frustrating, I think it makes sense to resist worsening that situation.)
