98928c83e0 Mark recently added pred4x4_down_left_mmxext as CONFIG_GPL. Although Holger 
initially said he'd be OK with relicensing, he also said he wanted to have
another look at the patch, and then he went on vacation, so let's play it
safe for now. We can consider removing this again later.

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).
