Detailed Description

Conversion pattern that transforms a linalg.slice op into:

1. A function entry alloca operation to allocate a ViewDescriptor.
2. A load of the ViewDescriptor from the pointer allocated in 1.
3. Updates to the ViewDescriptor to introduce the data ptr, offset, size and stride corresponding to the region of memory within the bounds of the parent view.
4. A store of the resulting ViewDescriptor to the alloca'ed pointer. The linalg.slice op is replaced by the alloca'ed pointer.
