    c++: fix ICE with [[deprecated]] [PR120756]

    Here we end up with "error reporting routines re-entered" because
    resolve_nondeduced_context isn't passing complain to mark_used.

            PR c++/120756

    gcc/cp/ChangeLog:

            * pt.cc (resolve_nondeduced_context): Pass complain to mark_used.

    gcc/testsuite/ChangeLog:

            * g++.dg/warn/deprecated-22.C: New test.
