David BlaikieandGeoff Romer 1cc699ddda Make heterogenous hash table lookup opt-in (#6950) ...

This still only works if the hash of the distinct types are identical
(so it still doesn't address the derived pointer v base pointer case -
well, not in the way we would want to address it, we could use this
change to make derived pointer and base pointer not compare equal, but
that's not very ergonomic)

I think in a follow up maybe I can use a `TranslatingKeyContext` to
translate `Derived*` to `Base*` in general.

No test coverage for this change, since it's a no-compile situation and
we don't seem to generally do no-compile tests.
