I have not tested this, but is it possible to enable these options via `-Cllvm-args=...` instead of using the unstable flags?
If so, I think this would be preferred in case the exact flags change before they become stable. It sounds like they are likely to change, see [1].
If not, no big deal since it would just need an update at a rust version bump.
