hum, so this is basicaly overloading the default_mem_sort_order for
architecture, right?
then I think it'd be easier just overload default_mem_sort_order directly
I was thinking more about adding extra (arch specific) loop to
sort_dimension__add or somehow add arch's specific stuff to
memory_sort_dimensions
