    c++: make -Wctad-maybe-unsupported respect complain [PR105143]

    We were attempting to issue a -Wctad-maybe-unsupported warning even when
    complain=3Dtf_none, which led to a crash in the first testcase below an=
d a
    bogus error during overload resolution in the second testcase.

            PR c++/105143

    gcc/cp/ChangeLog:

            * pt.c (do_class_deduction): Check complain before attempting
            to issue a -Wctad-maybe-unsupported warning.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp2a/nodiscard1.C: New test.
