The attached patch fixes the generated AVX2 assembly from thread
"[PATCH] x86: hevc_mc: remove non necessary moves". With it, it is
identical to what is generated without ec21721.
This should also be submitted to the x264 project, so that they can
also choose a better description/title for the patch.
This patch is mostly meant to check that it does fix generated
assembly for other users.
