> For the version with my patch, I simply put them around call to
> put_h264_chroma_mc8_mmx in put_h264_chroma_mc8_mmx_rnd and
> For the "before" timing, I created an intermediate function mimicking

> The global measures are without the _TIMER and the intermediate
> function, running with -benchmark.
