Enable asymptotic closed-loop encoding decision This commit enables asymptotic closed-loop encoding decision for the key frame and alternate reference frame. It follows the regular rate control scheme, but leaves out additional iteration on the updated frame level probability model. It is enabled for speed 0. The compression performance is improved: lowres 0.2% midres 0.35% hdres 0.4% Change-Id: I905ffa057c9a1ef2e90ef87c9723a6cf7dbe67cb
