Juergen Ributzka e612fc1230 [X86] Use min/max to optimze unsigend vector comparison on X86
Use PMIN/PMAX for UGE/ULE vector comparions to reduce the number of required
instructions. This trick also works for UGT/ULT, but there is no advantage in
doing so. It wouldn't reduce the number of instructions and it would actually
reduce performance.
