the ICE in #114275 was caused by transform_ty
in compiler/rustc_symbol_mangling/src/typeid/typeid_itanium_cxx_abi.rs encountering an unevaluated const, while expecting it to already be evaluated.

This PR could really use a better title, one that describes what it does. The "fixes ###" part can go in the PR description.

is this title better?

Yes. Also, this needs a test too

Please put it with the other CFI tests, probably in tests/ui/sanitize (but you should just grep for -Zsanitizer=cfi in the test suite).
