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.

9963b332d1 Use get_ue_golomb_31() where possible, almost all are just in headers 
though.

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 ...

a6493a8fbd Rename libavcodec/i386/ --> libavcodec/x86/. 
It contains optimizations that are not specific to i386 and
libavutil uses this naming scheme already.

cathedral +0.5% speed
