    d: Remove "final" and "override" from visitor method.
    
    This was added by the backport of an ICE in r12-8969.  While harmless,
    it was not until r13-758 that "final" and "override" were introduced to
    all visitor methods in the D front-end.  Removing it from the release
    branch just for consistency with the rest of the file.
    
    gcc/d/ChangeLog:
    
            * imports.cc (ImportVisitor::visit (OverloadSet *)): Remove "final"
            and "override" from visitor method.
