Add a pattern that bubbles up tensor.extract_slice through
tensor.expand_shape, and add a transform op to tensor dialect
to directly use this pattern.
This pattern enables tiling and fusing op chains which contain
tensor.expand_shape if added as a cleanup pattern of tile and fuse
utility.
Without this pattern that would not be possible, as
tensor.expand_shape does not implement the tiling interface.
In addition, registering this pattern as a cleanup pattern for
transform.structured.fuse.
The pattern was first implement in IREE project by
Quinn Dawkins and is being upstreamed.
