Add a new, more aggresive short circuit: short_circuit_low_temp_var = 3 to skip golden of any mode when variance is lower than threshold for low res. This change only affects speed = 8, low resolution. Metrics for avgPSNR/SSIM on rtc_derf (low resolution) show loss of 0.27/0.31%. On Nexus 6, the encoding time is reduced by ~2.3% on average across all low-res clips. Visually little change on rtc_derf clips. Change-Id: Ia8f7366fc2d49181a96733a380b4dbd7390246ec
