FFmpeg/libavcodec/x86/h264_intrapred_init.c
Andreas Rheinhardt 9bc527126c avcodec/x86/h264_intrapred: Remove obsolete MMX(EXT) functions 
x64 always has MMX, MMXEXT, SSE and SSE2 and this means
that some functions for MMX, MMXEXT and 3dnow are always
overridden by other functions (unless one e.g. explicitly
disables SSE2) for x64. So given that the only systems that
benefit from these functions are truely ancient 32bit x86s
they are removed.
