Removed MVC so that mv_err_cost() is always called while calculating
the mv cost.

Renames SSIM to VpxSSIM as an upscaled weighted SSIM metric, then prints
Y, U and V channels unweighted as well as a weighted but not scaled SSIM
score that's 8/1/1 parts Y/U/V (same as VpxSSIM).

For speed 8, it speeds up the encoding on android by 6% for QVGA and
7.4% for VGA with the new threshold. Overall PSNR is improved by 0.667
for rtc.

If enabled denoiser will only denoise the top spatial layer for now.

Added unittest for SVC with denoising.

This commit reworks the SSSE3 implementation of the forward 8x8
2D-DCT. It uses a cyclic rotation approach to the temporary xmm
registers. It reduces the average cycles from 158 to 154. The SSE2
version uses 169 cycles.

When aq=3 mode is on and the gf_cbr_boost is set: make sure golden frame
is always refreshed, and don't incorporate segement cost in qp setting
on the boosted golden frame.

Better performance on RTC set with gf_cbr_boost on,
for example with gf_cbr_boost=50, gains from ~0.5-3%.

Quality improved by 1.866 and 0.386 for two noisy clips (dark720p and
marcooffice720p), respectively.

Avoid the qp-clamping on gf/alt frame if gf_cbr_boost_pct is set.

Change only affect CBR mode when  gf_cbr_boost_pct is set.

This was much more amenable to optimization than the across filter.

Speed test shows 25% gain on vpx_idct16x16_256_add_neon(),
and vpx_idct16x16_10_add_neon() got trippled.
