    Refactor CmmLive and CmmSpillReload.
    
        * Move dead assignment elimination to CmmLive
        * Kill off dead code in CmmSpillReload related
          to non-splitting procpoints case
        * Refactor dual liveness transfer function to
          more closely mimic CmmLive's liveness transfer.
