I have only minor inline comments, good direction.

The PR is a bit big but I can see this requires touching everywhere in CIRGen and also LLVM lowering support, which is good end-to-end testing.

If there are things there are not needed right now, it'd be better to remove it for extra clarity. Have you checked that?
