I'm not really happy with this. The code for deferred declarations and
diagnosing name conflicts is complicated enough without adding the possibility
that the name of a declaration can change later.
Can we just suppress mangling in cases where we reference a symbol without
knowing if it's internal, then it turns out to be internal later?
