Correct bug in AutoHorizontal::getGCells() line probing. 

* Bug: In Anabatic::AutoHorizontal::getGCells(), the y coordinate used
    to perform the line probing for neighboring GCells, cannot use the
    segment constraints because they are not correctly set this early.
    Instead we have to rely on the global router having put them in the
    correct position (i.e. at the center of the GCell side).
      The y position must also be epsilon-decreased if it is on the
    border of the nothernmost GCell.
      This apply to AutoVertical as well.
* Change: In Anabatic::GCellTopology CTOR, when counting the RoutingPads
    of a GCell, compare gauge layers using their masks instead of the
    Layer itself. This allow for Analogic layers to be recognizeds.
