Andreas Rheinhardt 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)).

Christophe Gisquet 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.

James Darnley 17e7b49501 yadif: x86 assembly for 16-bit samples 
This is a fairly dumb copy of the assembly for 8-bit samples but it
works and produces identical output to the C version.  The options have
been tested on an Athlon64 and a Core2Quad.

Athlon64:
1810385 decicycles in C,    32726 runs, 42 skips
1080744 decicycles in mmx,  32744 runs, 24 skips, 1.7x faster
 818315 decicycles in sse2, 32735 runs, 33 skips, 2.2x faster

Core2Quad:
 924025 decicycles in C,     32750 runs, 18 skips
 623995 decicycles in mmx,   32767 runs,  1 skips, 1.5x faster
 406223 decicycles in sse2,  32764 runs,  4 skips, 2.3x faster
 387842 decicycles in ssse3, 32767 runs,  1 skips, 2.4x faster
 307726 decicycles in sse4,  32763 runs,  5 skips, 3.0x faster
