c318626ce2 x86: rename libavutil/x86_cpu.h to libavutil/x86/asm.h 
This puts x86-specific things in the x86/ subdirectory where they
belong.

110d0cdc9d rv40dsp x86: MMX/MMX2/3DNow/SSE2/SSSE3 implementations of MC 
Code mostly inspired by vp8's MC, however:
- its MMX2 horizontal filter is worse because it can't take advantage of
  the coefficient redundancy
- that same coefficient redundancy allows better code for non-SSSE3 versions

Benchmark (rounded to tens of unit):
        V8x8  H8x8  2D8x8  V16x16  H16x16  2D16x16
C       445    358   985    1785    1559    3280
MMX*    219    271   478     714     929    1443
SSE2    131    158   294     425     515     892
SSSE3   120    122   248     387     390     763

End result is overall around a 15% speedup for SSSE3 version (on 6 sequences);
all loop filter functions now take around 55% of decoding time, while luma MC
dsp functions are around 6%, chroma ones are 1.3% and biweight around 2.3%.

8d147f1f60 For rounding in chroma MC SSSE3, use 16-byte pw_3/4 instead of reading 8 bytes 
and then using movlhps to dup it into the higher half of the register.

2c166c3af1 Port latest x264 deblock asm (before they moved to using NV12 as internal 
format), LGPL'ed with permission from Jason and Loren. This includes mmx2
code, so remove inline asm from h264dsp_mmx.c accordingly.

14bc1f2485 Split h264dsp_mmx.c (which was #included in dsputil_mmx.c) in h264_qpel_mmx.c, 
still #included in dsputil_mmx.c and is part of DSPContext, and h264dsp_mmx.c,
which represents H264DSPContext and is now compiled on its own.

05aec7bb87 Separate DWT from snow and dsputil 
This moves the DWT functions from snow.c and dsputil.c to a file of
their own.  A new struct, DWTContext, holds the function pointers
previously part of DSPContext.

a6493a8fbd Rename libavcodec/i386/ --> libavcodec/x86/. 
It contains optimizations that are not specific to i386 and
libavutil uses this naming scheme already.
