    [turbofan] Add support for advanced reducers. · 7b33409b
    bmeurer authored
    An AdvancedReducer is basically a regular Reducer with an editor
    that can perform graph editing operations beyond changing or
    replacing the node that is currently being reduced. The GraphReducer
    is the default implementation of the AdvancedReducer::Editor interface.
    
    The ControlReducerImpl is now just an AdvancedReducer, which
    temporarily requires a Finish method in the reducer to implement
    the dead node trimming until we move that to the GraphReducer
    (which in turn requires that all loops are connected to End).
