With switching to clang-7.0.1 we got new warnings. With this change the
warnings are back to 0 for all configurations (excluding warnings in
third_party)

d931eb556b No need to shift in SSIM calculations 
We only need to shift in the encoder when the input bit depth
does not equal to the encoder internal bit depth.

a9ae351667 Add per-frame SSIM/PSNR stats to tools/tiny_ssim. 
Adds an optional output framestats.csv file that prints comparions
per-frame instead of averaged over the entire clip. It prints
per-channel and combined metrics for SSIM and PSNR.

605ca82e7f Add Y,U,V channel metrics and unweighted metrics. 
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).

fd4efde489 Add temporal-layer support to tiny_ssim. 
Permits skipping 0, 1/2 or 3/4 of the frames, corresponding to
temporal layers 2, 1 and 0 of a 3-temporal-layer encoding. 1/2
corresponds to TL0 in a 2-layer encoding.
