    * Change worklist to a set so that duplicates cannot happen
    * Add support for the invoke instruction
    * Avoid marking store and free instructions as overdefined, since they
      cannot produce a value anyway.
    * Inline the OperandChangedState implementation
    * Add isEdgeFeasible in preparation to fix a bug.  Right now it behaves
      exactly as before.
    * Remove obsolete comment about constant pools
