In some cases (see https://github.com/iree-org/iree/issues/16285), `memref.subview` ops can't be folded into transfer ops and sub-byte type emulation fails. This issue has been blocking a few things, including the enablement of vector flattening transformations (https://github.com/iree-org/iree/pull/16456). This PR extends the existing sub-byte type emulation support of `memref.subview` to handle multi-dimensional subviews with dynamic offsets and addresses the issues for some of the `memref.subview` cases that can't be folded.
