No reason to keep going one at a time when we know there are generally
better ways to handle loading a power-of-two number of low lanes.

12 (one 8 byte, one 4 byte), etc.
$ ninja -C out monobench; and out/monobench SkRasterPipeline_compile 300
Before: 46.946ns
After: 43.341ns
(This happens to be _lowp. Expect similar small speedups elsewhere.)
