At speed 2, due to the threshold scheme used, it is possible the rate and distortion assigned with INT_MAX value. The patch added checking to prevent the INT_MAX value is used in further calculation of RD scores. The patch also changed the assertion in rd_use_partition() to be mirror similar assertion in rd_pick_partition(). Change-Id: Idb52c543cc1e10abdf6e6a5d6e9cb535a42214dc
