I recommend not even counting xxlor at all, since the majority of
them come from vsx register copies and whether and how many we
generate seemingly varies with the phase of the moon, day of the
week, etc. etc.
If you really want to verify an xxlor count, you almost have to extract
the given test into it's own file so it's not corrupted by any of the
other tests and it has to be as small as possible and compiled with
a fair amount of optimization. Even then you may get some copies.
So I'd recommend just removing the xxlor counts altogether.
