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.
