This commit allows the encoder to account for additional chroma plane costs in the mode decision process, if the current block potentially contains significant color change. It improves the visual quality at very low bit-rates. The compression performance of dark720p is improved by 12.39% in speed 6. For jimred at 150 kbps, the PSNR of V component (red) increased by 0.2 dB, at the expense of about 5% increase in encoding time. Note that for sequences where the chroma components are fairly consistent, the encoding time increase is negligible. On average the rtc set compression performance is improved by 1.172% in PSNR and 1.920% in SSIM. Change-Id: Ia55b24ef23a25304f7ec9958fbf07fd6e658505c
