Review Comment:
Another question,
Device allocator types are specified externally (from like VM Init as
kPooled or kNaive). How could we enforce OpenCL device always use our new
allocator ?
Or
Do I use existing allocators (NaiveAllocator, PooledAllocator) and
CreateView will be specialized for device type kDLOpenCL alone ?
