Instead of using -1 to indicate jnt_comp is used or not, use a separate
variable.

Added convolve 1d functions for 1d-only sub-pixel interpolation, including
av1_convolve_x() function for "subpel_x_q4 == 0" case and av1_convolve_y()
function for "subpel_y_q4 == 0" case. Separated into different cases for
speeding up the codec(especially the decoder). The optimized version will
be added later.

This fixes a segfault in nightly tests for 32-bit clang builds.

Change-Id: Ie6de357443bc5bc5f3180791f34fce2566c242a9

Unify the non-zero counting and scan order update process for
the rectangular transform block sizes.

Change-Id: I5f2b833d7552ab67d4486b21d8d5e2fbf1bc217c

Support adaptive scan order update for flip ADST types of block
sizes 8x8 and below.

Change-Id: Ibcb3c9e9e0b8d397ef260a219b10a23e49758a63

Apply the adaptive scan order update to the significant regions
in large transform block sizes.

Change-Id: Ief6c37b09462a2ac5a26464b9aa336530b940839

Skip the last SB row counting for per frame adaptive scan order.
This allows enough time window for HW decoder to process the
scan order update for next frame decoding.

Change-Id: I8a3b48fe452c68c921d55dc76cc787f0a8e00e29

Limit the maximum transform block count to be 256 per adaptive
scan order model.

Change-Id: If6ae054d4427b784f05dd944747b6249b86f401b

Reduce the supported txfm kernel set from 9 to 4. This
substantially reduce the memory requirement in SRAM for hw design.

When forming a scaled prediction, we need to clamp against
the extended frame border which was set up when the relevant
reference frame was decoded. The width of this border actually
depends on the subsampling mode (for UV planes), but before this
patch we were always using the Y plane's border width.

This resulted in bad predictions when signalling a motion vector
which points far outside the reference frame. This patch fixes
the clamping, and restores the intended behaviour for out-of-frame
motion vectors.

Rename aom_lpf_horizontal_edge_16() to aom_lpf_horizontal_16_dual().

Change-Id: I43fb48b8cb91670d6de6527f9368acabdef2505a

Added a copy function (c version and sse2 version) for full-pixel motion
vectors. Here, the compound or non-compound cases were not separated, and
the left shifting were always done.

When the flag DISABLE_VARTX_FOR_CHROMA is on chroma is
constrained to always use the largest transform size
for the prediction unit size.
This is meant to simnplify the logic for transform size
selection for chroma with hopefully no loss.

Results:
lowres 30 frames, speed 1: -0.038% (a slight improvement).
lowres 30 frames, speed 0: 0.000% (noise level difference).

The file sad.c alone takes 35 seconds to compile.
This often happens to be on the build critical path.
Split it into two source files so they can be compiled in parallel.

The change can be temporarily reverted by setting ALLOW_128X32_BLOCKS
to 1 (for easy "is this better?" testing: we'll get rid of the option
once it's clear what we're doing).

Since this means we have to modify the "num_partition_types"
calculation in functions like read_partition, we move it into a helper
function called partition_cdf_length(). Doing this makes the bodies of
read_partition and write_partition somewhat simpler than they were.
