* Make intermediate arrays in av1(_highbd)_warp_affine_c signed,
to avoid integer overflow when multiplying an 'unsigned int'
by a negative 'int' value.
* Pad out arrays in masked_variance_test.cc so that the array
stride is a multiple of 16 bytes.
This fixes some UBSan errors in masked_variance_intrin_ssse3.c
related to unaligned loads of 32-bit values.

Earlier, intra prediction for rectangular blocks was performed by
running two steps of prediction on square sub-blocks.
With this experiment, we do proper intra prediction for rectangular
blocks. This ensures that we make use of all available neighboring
pixels especially for directional modes. For this, all the intra
predictors were updated to work with rectangular transform block sizes.
Performance improvements are small but free of cost:
All Intra frames:
lowres: -0.126
midres: -0.154
Video Overall:
lowres: -0.043
midres: -0.100

When frame_superres is on, loop-restoration should work
on the size of the upscaled frame and not on the internal
width and height in the common structure. This patch
makes the necessary changes on the encoder and decoder
side to enable that.

Exclude the test targets from Visual Studio and Xcode generation
runs unless explicitly requested. The test run takes hours, and

Earlier, the condition was negating all non-directional modes to check
if a mode is directional. This was error-prone, e.g. when a new
non-directional mode is added.
By checking for directional modes directly, we avoid such errors.

This terminates the computation for the warp error once
the frame error exceeds the best frame error found
so far to avoid unneccessary computation.

Comparing to lv_map experiment using the old av1_optimize_b
function, This change gives 0.8% gain on lowres and midres
datasets
Comparing to the baseline with greedy optimize_b, the lv_map
experiment will have 1.2% on lowres and 1.49% on midres.
The gains are similar to the one that under the condition of
turning off av1_optimize_b for baseline and lv_map.

This function will check if downgrading each coeff by one level
will reduce overall rd cost. If so, it will down grade the
coeff and update the effect and then move on to the next coeff.
In general, we found out that updating according to the
coding order will provide better coding performance.
The optimization order is as follows.
1) forward optimize coeffs == 1 or -1 only
2) backward optimize all coeffs

Implemented a MV refining search after the warped motion parameters were
found. Only 4 or 8 positions were checked so there was almost no impact
on encoder speed.

This reverts commit 846d67dd67.
Writing the scale every frame was not the right decision. The correct
thing to do will be also writing the superres scale when the size is
set using a previous frame.

cb4x4 itself should not require these sizes.
This simplifies compatibility with other experiments, since we can
first make them work with cb4x4 (which is now on by default), and
then worry about chroma_2x2 (which is not) in separate steps.
Encoder and decoder output should remain unchanged.
