Subject: [PATCH] Fix for Coriolis issue #6 (Katana core dump on ALU16).

* Bug: In Katana::AutoSegment::_preDestroy(), remove the segment from
    the source & target AutoContact cache.
      In LibreSOC/experiment7, weird placement caused fixed AutoSegment
    overlaping blockage to be deleteds. It seems to have never occured
    before (or at least, no ended up in core dump).
