(was duplicated in libavcodec/ppc/vc1dsp_altivec.c
nd libavcodec/ppc/mpegvideo_altivec.c, and will be
used in upcoming routines for h264_altivec.c)

moving another bit&1 out, this is as fast as with it in there, but it makes more sense with it outside of the loop

move the &1 out of the asm so gcc can optimize it away in inlined cases (yes this is slightly faster)

Originally committed as revision 6616 to svn://svn.ffmpeg.org/ffmpeg/trunk

this is faster on P3, should be faster on AMD, and should be slower on P4
its disabled by default (benchmarks welcome so we know when to enable it)

reading 8bit mem into a 8bit register needs 2 uops on P4, 8bit->32bit with zero extension needs just 1

first try of a handwritten get_cabac() for x86, this is 10-20% faster on P3 depening on if you try to subtract the START/STOP_TIMER overhead

remove bytestream_end checks, seems to work fine without them and the bitstream reader doesnt check for the end either
