Improve mlir-query tool by implementing `getBackwardSlice` and `getForwardSlice` matchers. As an addition `SetQuery` also needed to be added to enable custom configuration for each query. e.g: `inclusive`, `omitUsesFromAbove`, `omitBlockArguments`. Note: backwardSlice and forwardSlice algoritms are the same as the ones in `mlir/lib/Analysis/SliceAnalysis.cpp` Example of current matcher. The query was made to the file: `mlir/test/mlir-query/complex-test.mlir` ```mlir ./mlir-query /home/dbudii/personal/llvm-project/mlir/test/mlir-query/complex-test.mlir -c "match getDefinitions(hasOpName(\"arith.add f\"),2)" Match #1: /home/dbudii/personal/llvm-project/mlir/test/mlir-query/complex-test.mlir:5:8: %0 = linalg.generic {indexing_maps = [#map, #map], iterator_types = ["parallel", "parallel"]} ins(%arg0 : tensor<5x5xf32>) outs(%arg1 : tensor<5x5xf32>) { ^ /home/dbudii/personal/llvm-project/mlir/test/mlir-query/complex-test.mlir:7:10: note: "root" binds here %2 = arith.addf %in, %in : f32 ^ Match #2: /home/dbudii/personal/llvm-project/mlir/test/mlir-query/complex-test.mlir:10:16: %collapsed = tensor.collapse_shape %0 [[0, 1]] : tensor<5x5xf32> into tensor<25xf32> ^ /home/dbudii/personal/llvm-project/mlir/test/mlir-query/complex-test.mlir:13:11: %c2 = arith.constant 2 : index ^ /home/dbudii/personal/llvm-project/mlir/test/mlir-query/complex-test.mlir:14:18: %extracted = tensor.extract %collapsed[%c2] : tensor<25xf32> ^ /home/dbudii/personal/llvm-project/mlir/test/mlir-query/complex-test.mlir:15:10: note: "root" binds here %2 = arith.addf %extracted, %extracted : f32 ^ 2 matches. ```
