This coding tool is dependent on the tool of frame_marker. This tool
derives the frame sign bias directly from the frame offset. No sign
bias signaling is needed.

Add an experiment "tmp", which includes:
1. Always use larger block size while storing frame MVs and make
it consistent for CB4X4 or non-CB4X4 cases. Namely, use 8x8 for
4x4 mi size and 16x16 for 8x8 mi size.
2. Allocate smaller buffer for frame MVs and save memory usage.
3. Use nearby 8x8 or 16x16 location's previous frame MVs, and make
the logic simple.
4. Reduce the number of copying for frame MVs, that is very costly
in decoder.

Baseline decoder got 5+% speedup. Borg test on lowres set showed a
+0.009% PSNR difference before/after the patch.

cfl_alpha_dist, special care is given to scale the SSE

Earlier, the superres scale was in the form of:
N/16, where N ranged from 8 to 16.

We change this to the form:
8/D, where D ranges from 8 to 16.

This helps on the decoder side, by making it possible to work on 8x8
blocks at a time.

This optimization for speed was useful only when max tx-size
was 32x32. However with tx64x64 this was breaking certain assumptions
causing huge drops in coding efficiency. So I am removing this
optimization for now. This can be brought back latger as a speed feature.
The removal of this optimzation brings back the loss when 32x64
and 64x32 transforms are used.

The SSE4 function filter_intra_edge_sse4_1() reads data slightly
past the initialized part of the array. Those data are discarded
later, but causes a valgrind warning. This change avoids the warning
by initializing the array an extra +16 positions.

Reduce the context model size for key frame modes from 30240 bits
to 4500 bits, i.e., less than 1/6 of the original context model.
The coding performance loss on key frame is 0.14% for lowres and
noise level difference for video sequence. The loss on key frame
for midres is 0.05% and noise level for whole video. The change
on hdres kf coding is 0.015%.

This is undefined behaviour in C99 and could mislead the optimizer.
This fixes the ubsan warning, and still generates optimal code
(i.e an inlined 'sar' instruction).

Here, we're testing CONFIG_HIGHBITDEPTH but what we really depend upon
is the actual size of the coefficients.

Since the CONFIG_EXT_INTER #if/#endif lines have been removed, it's a
bit clearer what's going on here and this patch cleans up the code.

Firstly, the patch pulls the cheap checks on best_mbmode.ref_frame out
to the front of the block, so we needn't call gm_get_motion_vector at
all for compound predictions.

Next, second element of the zeromv array is never used, so we needn't
compute it.

Finally, the patch removes the calls to lower_mv_precision. These
shouldn't be needed, but it's not exactly obvious why not so the patch
adds some comments to gm_get_motion_vector to explain what's going on
and adds an assertion to make sure they are true. It also adds a call
to integer_mv_precision on the early return path of
gm_get_motion_vector, correcting an apparent bug when CONFIG_AMVR is
true.

This patch shouldn't make any difference to encoder or decoder
behaviour.
