This section needs a comment. Why do we look through USING_DECL for these
two kinds of member but not others?
I was looking explicitely for a FIELD_DECL or a TYPE_DECL because it
was crashing if I didn't. In fact, it was simply that DECL_NAME needs
at least tree_minimal, which OVERLOAD doesn't have. Is there a way to
properly check that DECL_NAME will succeed ?
You could check DECL_P first, but don't we want to return the OVERLOAD
here, too? You can use get_first_fn to get a FUNCTION_DECL out of
anything that satisfies is_overloaded_fn.
