Instead I now simulate unmerged RTTI instead: where I construct two type_info objects whose names are equal strings at different addresses. This does the same comparison code.

We _really_ shouldn't use the constructor for `type_info`. It's undocumented, so not considered an extension by libc++ and should be removed instead (as I do in #235739). I think we should simply disable the test for configurations where it doesn't work. If we can't generate two different typenames in a normal way there is no point in testing it.
