When global-motion is enabled, a considerable amount of encoder time is spent in the functions in corner_match.c. This patch optimizes those functions to be 3.5-4x as fast, leading to an end-to-end encoder speed improvement (on 20 frames of tempete_cif.y4m) of: 200kbps: ~26% faster 800kbps: ~19% faster 2800kbps: ~12% faster Change-Id: I04d3f87484c36c41eb5a1e86e814f2accbe86297
