Don't run UB in test suite This splits `ui/unsafe/union.rs` to make it so only the non-UB parts are run. It also means we can do more testing of the location of error messages (which are a bit different with the THIR unsafety checker). `union-modification.rs` has no UB (according to Miri), and `union.rs` has errors (but would have UB if not for those errors). Closes #95075. r? `@bjorn3`
