    c++: Crash when deducing template arguments [PR98790]

    maybe_instantiate_noexcept doesn't expect to see error_mark_node, but
    the new callsite I introduced in r11-6476 can pass error_mark_node to
    it.  So cope.

    gcc/cp/ChangeLog:

            PR c++/98790
            * pt.c (maybe_instantiate_noexcept): Return false if FN is
            error_mark_node.

    gcc/testsuite/ChangeLog:

            PR c++/98790
            * g++.dg/template/deduce8.C: New test.
