  Changed paths:
    M mlir/lib/Dialect/Linalg/Transforms/BubbleUpExtractSlice.cpp
    M mlir/test/Dialect/Linalg/bubble-up-extract-slice-op.mlir

  Log Message:
  [mlir] Do not bubble up extract slice when it is rank-reducing.

The bubble up logic was written by assuming the slice operation is
always a normal slice that outputs a tensor with the same rank.
