[FFmpeg-devel] [PATCH] x86: hevc_mc: replace simple leas by adds

Hi,

the impact is relatively important (3 to 25 cycles, ie up to 2%) so I
also include bench.patch if anybody wants to confirm the timings.

Although I thought openhevc's MC code was faster, the benchmarked
functions are faster in ffmpeg. I didn't investigate if there are any
MC functions much slower in ffmpeg or if there's something else
occurring.
