Cool. UIF/AND should already be handled (unless I really suck at
reading code) -- in fact UIF was one of the ones that I was fixing in
this series (although the fix is minor... depends how the cmp
instruction works, might not be necessary). The only instruction I saw
that wasn't in the list was ISSG. But perhaps I missed something.
