Check that a bridge only overrides members that are also overridden by the original member. This test is necessary only for members that have a value class in their type. Such members are special because their types after erasure and after post-erasure differ/. This means we generate them after erasure, but the post-erasure transform might introduce a name clash. The present method guards against these name clashes.
