Create Reduction Tree Pass Implement the Reduction Tree Pass framework as part of the MLIR Reduce tool. This is a parametarizable pass that allows for the implementation of custom reductions passes in the tool. Implement the FunctionReducer class as an example of a Reducer class parameter for the instantiation of a Reduction Tree Pass. Create a pass pipeline with a Reduction Tree Pass with the FunctionReducer class specified as parameter.
