In super_block_uvrd(),if is_cost_valid == 0, all return parameters,
i.e. rate, distortion, skippable, and sse, are reset.
So, should not call txfm_rd_in_plane() if is_cost_valid == 0.
Also, the bug causes av1_xform_quant() to see invalid diff signal
since av1_subtract_plane() is not called in super_block_uvrd().

This flag was already added to aomedia/master, so bringing it back to
webm/nextgenv2, as part of an effort to get the two codebases in sync.

To get ready for pulling AV1 to nextgenv2
Replace the experimental flag by MOTION_VAR. Rename major variables.

Adds the functionality to return the rate cost due to
coefficients without doing full search of all modes.
This will be subsequently used in various experiments,
including in new_quant experiment to search quantization
profiles at the superblock level without repeating the
full mode/partition search.

- Unit tests are added for AVX2 SIMD.
- Encoder speed improvement:
AV1 baseline and EXT_TX, three 1080p sequences at bitrate:
800 Kbps, 2 Mbps, 6 Mbps, on i7-6700 CPU, average
user level time reduction: 3.86%.

Disable rect_tx because we only support 4x4 Walsh-Hadamard transform
in lossless mode.
Fixes failure in ./test_libaom --gtest_filter=*Large*ScreencastQ0/1
Configuration: --enable-experimental --enable-var-tx --enable-rect-tx
--enable-ref-mv --enable-ext_intra --enable-ext_tx --enable-debug

this matches style guidelines and stabilizes successive runs of
clang-format across the tree. remaining types should be address in
successive commits.

This makes the code in select_tx_size_fix_type match the
corresponding code in pack_inter_mode_mvs.

Bitstream syntax:
For a rectangular inter block, 'rect_tx' flag is sent to indicate if
the biggest rect tx is used. If no, continue to decode regular
recursive tx partition.

Uses an array to map block sizes, y tx sizes, and subsampling
factors to various transform sizes for UV.
Results improve by 0.1-0.2%

This patch completes the global motion experiment
implementation. It modifies the format of the motion
parameters to use the mv union to facilitate faster
copying and checks for parameters equal to 0 that occur
frequently in rdopt. The rd decisions for the global motion experiment
have also been added to rdopt.
