Do we really need this?

AFAICT, the stub is only generated when we do `EmitInlinedInheritingCXXConstructorCall`. Those inheriting constructors don't support the `debug_transparent` attribute anyway. I think it would be sufficient to just add a test that ensures we do the right thing for inlined functions.
