- Add support fef memory_space_cast to strided metadata expansion and
narrow type emulation
- Add support for expand_shape to narrow type emulation (like
collapse_shape, it's a noop after linearization) and to
expand-strided-metadata (mirroring the collapse_shape pattern)
- Add support for memref.dealloc to narrow type emulation (it is a
trivial rewrite) and for memref.copy (which is unsupported when it is
used for a layout change but a trivial rewrite otherwise)
