52cb7981e2 Redo r12838, this time using svn copy to create h264_i386.h from cabac.h. 
Move decode_significance_x86() and decode_significance_8x8_x86() to
i386-specific file from cabac.h.
New file is h264-oriented and only included from h264.c
Resolves compilation when configured with --disable-optimizations due to
decode_significance_8x8_x86 using last_coeff_flag_offset_8x8, which is
only defined in h264.c

96275520a3 Fix H.264 interframe decoding when compiling with icc. Patch by Loren 
Merritt:

"It seems that icc copies the constants from their global var onto the
stack, at which point they're not aligned, hence the crash.
[This change] really shouldn't mean anything different, but maybe it'll
confuse icc into not performing that 'optimization'."

ae904fd028 Fix issue #301: 
summary of changes:
- Use MANGLE when loading some constants into MMX registers.
- Convert those constants to non-static and thus add ff_ prefix.
- Remove last parameter of MSPEL_FILTER13_CORE (was constant).
- Use of "+r" instead of stricter but unnecessary "+g".
- Use of REG_c and direct loading of some of the above.

629750290f avoid overflow in the 3rd lifting step, this now needs mmx2 at minimum 
(patch for plain mmx support is welcome ...)

3e0f7126b5 update mmx code to latest snow changes 
note, the code likely can overflow and thus needs some more changes
sse2 updated too but disabled as it is untested

d593e32983 use 16bit IDWT (a SIMD implementation of it should be >2x faster then with 
the old 32bit code)
disable mmx/sse2 optimizations as they need a rewrite now

ce611a27be Change rounding of the horizontal DWT to match the vertical one. 
This allows some simplifications and optimizations and should
not have any effect on quality.
