Hmm, I might be doing something wrong, but this doesn't seem to actually fix the issue encountered in #121571; rebased on this commit and still running into the same ICE. I pushed the rebased version onto that branch for you to test, which should also help verify if it's still breaking on CI and isn't just my setup.

EDIT: Yup, it's still happening on CI. #121571 (comment)

EDIT 2: Oh, it's just that the bug is in the bootstrap compiler. :(

I would like this in beta so that the stage0 compiler does not ICE if it gets passed -Zmir-opt-level=0. Yes I can work around this issue without huge difficulty, but the diff here is so small.
