intel/eu: Add the RNDU opcode

Browse Source 
We don't want to use it on gen5 and earlier because only RNDD can be
done with a single instruction and we can implement RNDU(x) as -RNDD(-x)
so it's better to just do that when we have the instruction.  On gen6
and above, we may as well just use the right instruction.
