Improve error message when trying to do overloading resolution of alternatives introduced by refinements.
As i8736 shows, it's not so simple to identify overloaded members introduced by refinements, since this can
arise through intersection and de-aliasing. So our best bet is to make the error message clearer at the
point of overloading resolution.
