1d3b14cac2 yadif: remove repeated check on width
The filter already checks that width (and height) are greater than 3.

0a5814c9ba yadif: x86 assembly for 9 to 14-bit samples
These smaller samples do not need to be unpacked to double words
allowing the code to process more pixels every iteration (still 2 in MMX
but 6 in SSE2).  It also avoids emulating the missing double word
instructions on older instruction sets.

Like with the previous code for 16-bit samples this has been tested on
an Athlon64 and a Core2Quad.

Athlon64:
1809275 decicycles in C,    32718 runs, 50 skips
 911675 decicycles in mmx,  32727 runs, 41 skips, 2.0x faster
 495284 decicycles in sse2, 32747 runs, 21 skips, 3.7x faster

Core2Quad:
 921363 decicycles in C,     32756 runs, 12 skips
 486537 decicycles in mmx,   32764 runs,  4 skips, 1.9x faster
 293296 decicycles in sse2,  32759 runs,  9 skips, 3.1x faster
 284910 decicycles in ssse3, 32759 runs,  9 skips, 3.2x faster
