Alex Zinenko	2791162b01	[mlir] make memref.subview produce strided layout ... Memref subview operation has been initially designed to work on memrefs with strided layouts only and has never supported anything else. Port it to use the recently added StridedLayoutAttr instead of extracting the strided from implicitly from affine maps.

Matthias Springer	6c3c5f8069	[mlir][memref] Improve type inference for rank-reducing subviews ... The result shape of a rank-reducing subview cannot be inferred in the general case. Just the result rank is not enough. The only thing that we can infer is the layout map. This change also improves the bufferization patterns of tensor.extract_slice and tensor.insert_slice to fully support rank-reducing operations.
