Should all reflection APIs that return possible skolems be changed to call widenSkolem? For example, x.prefix in TermRef.unapply and TypeRef.unapply could both return skolems. IMO, this is too easy to get wrong and we should instead handle skolems by exposing their parent trait SingletonType in the reflection API.

Not sure if that would be a backwards compatible change.
