Revision: 8649
Log message:

      - Changed the filter to add a "Perv!select_crw" label to all the annotations
        on conditional rewrites.
      
      - Added simpleReduceC that calls reduceC while ignoring the conditional
        rewrites.
      
      TODO:
      - Add the "select_crw" label to manual reduce adds (where approproate)
      
      - Try adding simpleReduceT to autoT with a higher priority than the regular
        reduceT (possibly even to AutoNormal and not just AutoComplete)
