01c5779f56 x86: Drop some unnecessary YASM ifdefs
Dead code elimination is enough to avoid undefined references in these cases.

This reverts commit fc5fe4804f, reversing
changes made to ffe3350098.

The factoring is broken; it's not calling the ssse3 code anymore, and
calling the mmx2 code with bad alignment. It also broke some FATE
instances.

b0ef0ae776 yadif: restore speed of the C filtering code
Always use the special filter for the first and last 3 columns (only).

Changes made in 64ed397 slowed the filter to just under 3/4 of what it

2d66fc543b lavfi/gradfun: fix rounding in MMX code.
Current code divides before increasing precision.

Also reduce upper bound for strength from 255 to 64.  This will prevent
an overflow in the SSSE3 and MMX filter_line code: delta is expressed as
an u16 being shifted by 2 to the left. If it overflows, having a
strength not above 64 will make sure that m is set to 0 (making the
m*m*delta >> 14 expression void).

A value above 64 should not make any sense unless gradfun is used as
a blur filter.

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

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
