Add CONFIG_DAALA_DCT8 experiment.
This experiment replaces the 8-point Type-II DCT and 8-point Type-IV DST scaling vp9 transforms with the 8-point orthonormal Daala transforms. These have reduced complexity and are perfect reconstruction at the cost of a slightly worse coding performance. This is because the Daala transforms expect the input to be shifted by 4 bits but the output scale of the vp9 transforms is only 3 bits. subset-1: monty-square-baseline-subset1 -> monty-square-dct8-subset1@2017-07-17T21:37:44.281Z PSNR | PSNR Cb | PSNR Cr | PSNR HVS | SSIM | MS SSIM | CIEDE 2000 0.0019 | -0.0011 | -0.0585 | -0.0111 | 0.0305 | 0.0317 | 0.0187 objective-1-fast: monty-square-baseline-o1f -> monty-square-dct8-o1f@2017-07-17T21:37:15.735Z PSNR | PSNR Cb | PSNR Cr | PSNR HVS | SSIM | MS SSIM | CIEDE 2000 0.0285 | 0.0129 | -0.5080 | 0.0529 | 0.0345 | 0.0441 | 0.0054 Change-Id: I2b775495398fb717204a295397c3c5e3ca938183
