In preparation for adding more 1D variants with ADST/FlipADST/etc.
BDRATE actually improves by 0.21% on lowres.

Instead of testing all interpfilter-BMC/OBMC combinations, we choose
the best interpolation filter based on regular inter prediction.
Reduction in encoding time: ~10%
Drop in performance gain: 0.08% lowres, 0.04% midres

Temporarily disable transform type selection for 32x32 transform
block size. This speeds up the encoding process. For bus at CIF
150 frames, the encoding time goes from 896s -> 762s (11% faster).
The compression performance for lowres set is improved by 0.15%,
and -0.029% for hdres.
Change-Id: If239b272970eb302150bec13b8cf192fbe045332
Using the up-sampled reference frames in sub-pixel motion search is
enabled as a speed feature for good-quality mode speed 0 and speed 1.

Coding gain on screen_content is 12.2% (was 6.6%).
Some features such as frame-level color buffer, adaptive
entropy coding, are coming in future patches.

This commit enables the hybrid 1-D/2-D transform coding scheme for
high bit-depth setting. It improves the compression performance of
ext-tx experiment by 0.98% for lowres_all set.
Change-Id: Ic27f5037f2c36b095a93b9f15dbae34bdcdf00aa
This commit enables the 1-D transform to use Manhattan grid vertical
and horizontal scan order for transform coefficient entropy coding.
Enabled in inter prediction mode, the hybrid 1D/2D transform coding
scheme outperforms the 2D-DCT based coding system used in VP9 by
lowres_all 1.7%
hdres_all 1.4%
As one coding option, in addition to the existing 17 other transform
types in ext-tx experiment, the 1D/2D hybrid transform improves
the coding gains:
lowres_all 2.2% -> 3.0%

- Implemented fdst16_sse2(), fdst16_8col() against C version: fdst16().
- Turned on 7 DST related hybrid txfm types in vp10_fht16x16_sse2().
- Replaced vp10_fht10x10_c() with vp10_fht16x16_sse2() in
fwd_txfm_16x16().
- Added vp10_fht16x16_sse2() unit test against C version:
vp10_fht16x16_c() (--gtest_filter=*VP10Trans16x16*).
- Unit test passed.
- Speed improvement: 2.4%, 3.2%, 3.2%, for city_cif.y4m, garden_sif.y4m,
and mobile_cif.y4m.
Change-Id: Ib30a67ce5d5964bef143d588d0f8fa438be8901f
Pixel domain distortion calculation is enabled for the rd loop of
inter sub8x8 and intra 4x4 cases.
Coding gain: 0.124% derflr, 0.122% derfhd
Change-Id: I43b47fe81b4f5ccc1c66bc626bd310c413a1ed87
- Inherited base class TransformTestBase to derived class VP10Trans8x8HT.
- Employed RunCoeffCheck() to test vp10_fht8x8_sse2() against C reference
function vp10_fht8x8_c().
- fdst8_sse2() related seven hybrid transform cases are covered in this
test.
- Test passed (4 test cases w/o EXT_TX; 16 test cases with EXT_TX).
