- Integrate 5 flip transform types for each 4x4, 8x8, and 16x16
block, for experiment, EXT_TX.
- Encoder speed improves about 12%-15%.
- Update the unit tests for bit-exact result against C.
Change-Id: Idf27c87f1e516ca5b66c7b70142477a115404ccb
- Tx_type: DCT_DCT, DCT_ADST, ADST_DCT, ADST_ADST.
- Update vp10_fht16x16_test.cc to do bit-exact test against
latest C version.
- HBD encoder speed improves ~1.8%.
Change-Id: Icfc799a212e5289bcf6cedcae3722032133a2bc6
- Wrote function: fidtx8_sse2() and fidtx16_sse2().
- Turned on vp10_fht8x8_sse2()/vp10_fht16x16_sse2() for new types.
- Updated 8x8/16x16 unit tests for accuracy/speed.
- Running 20K times with random numbers and getting through
tx type from V_DCT to H_FLIPADST, SSE2 speed improvement:
8x8: ~131%
16x16: ~66%

Makes a set of 16 transforms total, adding all 1D
combinations of ADST and FlipADST, and removng all DST
transforms.
lowres, midres both improve by about 0.1% and hdres by
-0.378% in BDRATE but with fewer transforms that are also
simpler.
Further experiments to continue later.

- 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.
