337e3fd990 Disable usage of ff_h264_idct_add_altivec since AltiVec versions of h264_idct_add16, 
h264_idct_add16intra, h264_idct_add8 need to be implemented.

Add C version of ff_h264_idct8_dc_add in AltiVec so that ff_h264_idct8_add_altivec
can be used.

05d3fd44d7 Integrate get_te0_golomb() calls into the code, this allows some checks 
to be avoided and the function is pretty small.
3% speedup, though this is probably due to changed inlining and not directly
this change.

d42fc4a8ca Use the new VLC table for the first non trailing coeff too. 
Sadly only 5 cycles faster here on pentium dual. So maybe the
complexity is not worth it and this should be reverted ...
