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.
