    Instantiate default arguments/member initializers once.

            * init.c (get_nsdmi): Remember NSDMI instantiations.
            * parser.c (inject_this_parameter): Be more picky about
            current_class_ptr.
            * pt.c (tsubst_copy): Simplify 'this' handling.
            (tsubst_default_argument): Remember default argument
            instantiations.  Take parameter number.
            (tsubst_default_arguments): Pass it.
            * call.c (convert_default_arg): Likewise.
