Chia-hung Duan c484c7dd9d [mlir-reduce] Reducer refactor. 
* A Reducer is a kind of RewritePattern, so it's just the same as
writing graph rewrite.
* ReductionTreePass operates on Operation rather than ModuleOp, so that
* we are able to reduce a nested structure(e.g., module in module) by
* self-nesting.

Mauricio Sifontes 8f4859d351 Create Optimization Pass Wrapper for MLIR Reduce 
Create a reduction pass that accepts an optimization pass as argument
and only replaces the golden module in the pipeline if the output of the
optimization pass is smaller than the input and still exhibits the
interesting behavior.

Add a -test-pass option to test individual passes in the MLIR Reduce
tool.
