Martin Nordholts d46df80c73 rustc_codegen_ssa: Don't let IncorrectCguReuseType errors get lost
In [100753], `IncorrectCguReuseType` accidentally stopped being emitted.
Begin emitting it again rather than just blindly dropping it, and adjust
tests accordingly.

[100753]: 706452eba7 (diff-048389738ddcbe0f9765291a29db1fed9a5f03693d4781cfb5aaa97ffb3c7f84)
