Simplify MV parsing, removes laying out 2 or 4 (16x8/8x8/8x16) MVs over all
16 subblocks (since we no longer need that), which should also lead to a minor speedup. Originally committed as revision 23854 to svn://svn.ffmpeg.org/ffmpeg/trunk |

Optimize split MC, so we don't always do 4x4 blocks of 4x4pixels each, but
we apply them as 16x8/8x16/8x8 subblocks where possible. Since this allows us to use width=8/16 instead of width=4 MC functions, we can now take more advantage of SSE2/SSSE3 optimizations, leading to a total speedup for splitMV filter of about 10%.
