  * MERGED: The ru_local field of a CoreRule is False for implicit Ids
  simonpj at microsoft.com**20070330144344
   
          MERGE to 6.6.1
   
   For class-ops, record selectors, data constructors, we want the ru_local
   field of the Rule to be False.  We do not attach the rule to the binding
   for the Id, because there simply isn't a binding until the code gen stage.
   
   (NB: the ru_local field is different to the orphan-hood of the rule.)
   
   This fixes a bug that meant that RULES on class ops were never exported.
