More generic criterion for finding under minimum area segments.

* Change: In AutoSegment::isMiddleStack(), after checking for obvious
    non-candidates, relies on axis-to-axis wirelength instead of topological
    criterions. We will not be able to account all the topologies that
    may cause problem. So consider every segment whose length is below
    one perpandicular pitch.
