Use rowend instead of tie in ClockTree for removed clock buffers. 

* Bug: In Cumulus, in ClockTree.py, do not use "tie_x0" which is 2 pitch
    wide to fill the free space left by clock-tree removed (unused)
    buffers. If the buffer size width is odd (in pitch), it will left
    a gap in the WELL. That was the cause of DRC notch errors.
      Instead use "rowend_x0" which is one pitch wide.
      Should use the same mechanism as in Mauka InsertFeed.
