Rollup merge of rust-lang#128616 - compiler-errors:mir-inline-tainted, r=cjgillot Don't inline tainted MIR bodies Don't inline MIR bodies that are tainted, since they're not necessarily well-formed. Fixes rust-lang#128601 (I didn't add a new test, just copied one from the crashes, since they're the same root cause). Fixes rust-lang#122909.

This is perhaps a dumb question, but why are any optimizations performed at all when errors are present? |

When all errors are present? Because we don't want global state to affect local computations, iirc. |
