        * var-tracking.c (values_to_unmark): New variable.
        (find_loc_in_1pdv): Clear VALUE_RECURSED_INTO of values in
        values_to_unmark vector.  Moved body to...
        (find_loc_in_1pdv_1): ... this.  Don't clear VALUE_RECURSED_INTO,
        instead queue it into values_to_unmark vector.
        (vt_find_locations): Free values_to_unmark vector.
