After some more thoughts I'm convinced that this patch was
a bad idea, please drop it.

The rationale being that even if there is a lot of pair of
dual instructions ('Xi - Yi' / 'Yi - Xi'), their hashing
will still be spreaded relatively evenly because there
will be a lot of Xi & Yi but with the patch *every*
instruction like 'Xi - Xi' will give the same hash
indenpendently of the Xi.
