4b4f92780e Shuffle extension word order. 
The primary objective here is simplifying index calculation, but as per the note it does also potentially open up options with regard to packing in the future.

9b4048ec6e The address size modifier doesn't seem to affect far address sizes. 
It's meant to affect only instructions with operands that reside in memory, I think. So probably only ::DirectAddress in my nomenclature. More research to do.
