Nicolas Vasilache 0b47f74037 [Linalg] Add a slice op ... This CL adds a linalg.slice op with the proper roundtripping test. A slice op allows taking subviews that may be rank-reducing (if some indexing is of index type) or not (if all indexings are of linalg.range type). A slice must be constructed directly from a base view (no chains of slices may exist in the IR). Helper functions that fold will be provided for construction if/when necessary. This also renames base_view to view. -- PiperOrigin-RevId: 244406827		2019-04-23 22:01:10 -07:00
