When you say "load is multiple of 4 bytes away from a 8-byte aligned  
data"
it is not clear whether it is 16-byte aligned or not. However, "load  
is 4 bytes
away from a 8-byte aligned data" is clear - it is aligned at 12-byte  
and not
16-byte.

However, that means, for loops this becomes "load is N bytes away
from a 8-byte aligned data" where N is dependent on IV.
