Martin Storsjö 557c1675cf arm: vp9mc: Minor adjustments from review of the aarch64 version 
This work is sponsored by, and copyright, Google.

The speedup for the large horizontal filters is surprisingly
big on A7 and A53, while there's a minor slowdown (almost within
measurement noise) on A8 and A9.
