Enhance "case" code completion in C++ to suggest qualified names for
enumerators when either the user intentionally wrote a qualified name
(in which case we just use that nested-name-specifier to match
the user's code) or when this is the first "case" statement and we
need a qualified name to refer to an enumerator in a different scope.
