    c-family: Avoid ICEs on calls to internal functions [PR95963]

    The following testcase ICEs since recent Martin's -Wnonnull changes,
    we see a CALL_EXPR and ICE because CALL_EXPR_FN is NULL, which is
    valid for internal function calls.  Internal function calls don't have a
    function type, and will never have format_arg attribute on them nor will
    serve as the i18n routines -Wformat cares about.
