    c++: No aggregate CTAD with explicit dguide [PR98802]

    In my implementation of P2082R1 I missed this piece: the aggregate
deduction
    candidate is not generated if the class has user-written deduction guides.

    gcc/cp/ChangeLog:

            PR c++/98802
            * pt.c (deduction_guides_for): Add any_dguides_p parm.
            (do_class_deduction): No aggregate guide if any_dguides_p.
