Updated patch to address x86_64 performance issues.
This updated patch reverts the swap_commutative_operands_with_target removal
from the previous patch, since it seems x86_64 still relies on this for some
benchmarks. The change doesn't seem to affect the POWER6 performance benefits
we were seeing with the older patch.
