I assume this include made was added as the enum is defined in that header. Actually, the header is only included in the two new `mlir/include/mlir/Conversion/MathToEmitC/{MathToEmitC,MathToEmitCPass}.h` header files. Maybe there is a better place to define the enum, `Transforms/Passes.h` seems not the best place. @simon-camp any suggestion?
