    * class.c (type_has_user_declared_move_constructor): New.
    (type_has_user_declared_move_assign): New.
    (add_implicitly_declared_members): Add lazy copy ops
    even if there's a move.
    * method.c (lazily_declare_fn): Delete implicit copies
    if there's a move.
    (maybe_explain_implicit_delete): Explain this.  Use inform rather
    than error.
