    c++: Fix up user_provided_p [PR81349]

    The standard says: "A function is user-provided if it is user-declared and
    not explicitly defaulted or deleted on its first declaration."
    I don't see anything about function templates having different rules here,
    but user_provided_p does return true for all TEMPLATE_DECLs.

    The following patch fixes it by treating as user-provided only templates
    that aren't deleted.

            * class.c (user_provided_p): Use STRIP_TEMPLATE instead of
returning
            true for all TEMPLATE_DECLs.
