intel/eu: Set flag [sub]register number differently for 3src
Prior to gen8, the flag [sub]register number is in a different spot on
3src instructions than on other instructions. Starting with Broadwell,
they made it consistent. This commit fixes bugs that occur when a
conditional modifier gets propagated into a 3src instruction such as a
MAD.
