   Thanks for the remind @tqchen !
   For the `data_alignment` , I have an extra question that whether the 
`data_alignment` is about the `data` ptr address or about 
   the first element's address?
   
   If the former, I think we should ensure the alignment property every time we 
create alias buffer to existing buffer vars, no matter whether the 
`elem_offset` is non-zero. I would like to change the alignment handling in 
`StorageRewrite` pass since it has explicit buffer aliasing impl code path.
