This commits adds a shift stage for FASTSSIM computaton when source
bit depth is different from working bit depth, to make sure metric
results are calculated in bit_depth consistent with source.

This commit adds the ability to shift down the working buffer when
source bit_depth is different than working bit_depth. It does so
by shift down to be consistent with source bit_depth.

This makes all metric computation to locate at some place, also gets
rid of duplicate code between vp9 and vp10.

Adds new 32x32 masked 1-d transforms that combine 1-D length-16
DCT with length-16 identity transforms.
To be continued in subsequent patches.

vpx_highbd_lpf_horizontal_edge_8 to avoid passing a count parameter

Using this we can eliminate large numbers of calls to predict intra,
and is also faster than most of the variance functions it replaces.
This is an equivalence transform so coding performance is unaffected.
Encoder speedup is approx 7% when var_tx, super_tx and ext_tx are all
enabled.

This commit adds computation of PSNRHVS for highbitdepth build, it
also adds tests to make sure the calculation of psnrhvs metric for
10 and 12 bit correct.

This commit adds the computation of fastSSIM for highbitdepth build,
it also modifies the hbdmetric test to be more generic and applicable
for fastSSIM.
The 255 used for calculating ssim constants c1 and c2 is not exactly
scaled by 4x and 16x to 1023 and 4095, therefore requries the metric
test to have a thresold more tolerant than 0, currently at 0.03dB.

There were a number of compiler warnings:
1. int16_t to uint8_t in recon_intra.c;
2. double to float conversions in psnrhvs.c
3. intptr_t to int in quantize.c
4. size_t to int32_t in decoder.c

the results along the top and left border are then stored with a moving
window into the vector.
~40-67% faster on ARM, ~40-77+% on x86 depending on the block size.

Temporaly disable warning for unused function for vp10, needs clean
out the warnings before re-enable the flag for vp10.

This commit changes SSSE3 optimized idct8x8 functions to work with
highbitdepth build.
With this commit and the previous one that enabled SSSE3 idct32x32
functions, tests showed virtually no difference on decoding speed for
file fdJc1_IBKJA.248.webm for the build with -enable-vp9-highbitdpeth
option and the build without the option.

This commit changes the SSSE3 assembly functions for idct32x32 to
support highbitdepth build.
On test clip fdJc1_IBKJA.248.webm, this cuts the speed difference
between hbd and lbd build from between 3-4% to 1-2%.
