The memory_region_dispatch_{read|write} operand "unsigned size" is
being converted into a "MemOp op".

Introduce no-op size_memop to aid preparatory conversion of
interfaces.

Once interfaces are converted, size_memop will be implemented to
return a MemOp from size in bytes.

Return type should remain unsigned until patch 11.
