Prefer even-odd D-register pairs. We are sometimes allocatinog from the DPair register class which contains odd-even pairs in addition to the Q registers. Place the Q registers first in the DPair allocation order as they can be copied with a single instruction. The odd-even pairs should only be allocated as a last resort. llvm-svn: 153699 GitOrigin-RevId: 2f2897372ac3b502f679bdc24c938d5bd936e109
