Is this even reachable? If not, could you just say UNREACHABLE(); return
Type::Any();? (Same below.)

If we leave it Number, it should be correct, and we won't have to touch it
if/when it does become reachable.

As discussed with jarin@ offline, I put UNREACHABLE() here because at the moment
this type information is not used at the moment, and it will be deleted soon
anyways.
