dd68d4db43 MMX, MMX2, SSE2 and SSSE3 optimizations for pred16x16/8x8_plane H264 intra 
prediction (plus some with different rounding for svq3/rv40). Speedup (for
SSSE3) about ~6-fold, 3.6% faster overall with cathedral sample.

de1c253bab Split intra prediction initialization (i.e. assigning of function pointers) 
into its own file, it doesn't belong in h264dsp_mmx.c (much less so in
dsputil_mmx.c).
