Richard Smith e8292b10a6 [modules] When determining whether a name from a module replaces a name we ...

already have, check whether the name from the module is actually newer than the
existing declaration. If it isn't, we might (say) replace a visible declaration
with an injected friend, and thus make it invisible (or lose a default argument
or an array bound).
