The usual: the code didn't type-check, so we shouldn't even try to const-eval it.

Rollup merge of rust-lang#125451 - oli-obk:const_type_mismatch, r=compiler-errors Fail relating constants of different types fixes rust-lang#121585 fixes rust-lang#121858 fixes rust-lang#124151 I gave this several attempts before, but we lost too many important diagnostics until I managed to make compilation never bail out early. We have reached this point, so now we can finally fix all those ICEs by bubbling up an error instead of continueing when we encounter a bug.
