enable CMOV_IS_FAST as its faster or equal speed on every cpu (duron, athlon, PM, P3) from which ive seen benchmarks, it might be slower on P4 but noone has posted benchmarks ...

(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)


git-svn-id: file:///var/local/repositories/ffmpeg/trunk@6616 9553f0bf-9b14-0410-a0b8-cfaf0461ba5b

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)
