4d7128be9a avfilter/x86/vf_yadif: Remove obsolete MMXEXT functions 
The only system which benefit from these are truely ancient
32bit x86s as all other systems use at least the SSE2 versions
(this includes all x64 cpus (which is why this code is restricted
to x86-32)).

ddea3b7106 x86/yadif-10: remove duplicate ABS macro 
And use the x86util ones instead, which are optimized for mmxext/sse2.
About ~1% increase in performance on pre SSSE3 processors.

9107612818 x86util: add and use RSHIFT/LSHIFT macros 
Those macros take a byte number as shift argument, as this argument
differs between MMX and SSE2 instructions.

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
