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
