It's nice to have this for completeness sake. However I don't understand how the IR generated might with
 
1) extract all elements as scalars
2) insert scalars into small tiles
3) insert small tiles into final big tile 

might be better than 

1) extract all elements as scalars
2) insert scalars directly into big tile 

is there an example of this?
