Some combination of recent Rust changes (between 3d86494a0d01 and aa57e46e24a4 from what I can tell) and changes in LLVM 21 (not recently, as best I can tell) have caused this test to start showing the behavior we want, so it's time to move this test to a proper place and mark it as fixed on LLVM 21.
