This test is failing when no experiments are turned on. PSNR is
31.96 when the threshold is 32.

If it's creating problems with some experiments, disable it under the
actual conditions where it doesn't work and file a bug.

We can optimize wedge partition selection by pre-computing the
residuals of the 2 underlying predictors, and then blend these
to compute the sse of the compound predictor, without actually
having to compute and subtract the compound predictor.
Similarly we can pre-compute a proxy array which we can use to
cheaply check which mask sign would have lower sse.
Details are in wedge_utils.c.
Mathematically these are equivalence transformations, but due to the
finite precision the encoder output will be perturbed, though on
average this should make 0% difference.
ext-inter gains about ~4.5% speedup.

xd->plane[0].n4_h and xd->plane[0].n4_w are not set at that point
when using supertx.
While this fixes the immediate crash described in the referenced
bug report, there are still issues in the ref-mv experiment that
causes these tests to fail, so they are kept disabled.

This is to replace vp10/common/reconinter.c:build_masked_compound.
Functionality is equivalent, but the interface is slightly more
generic.
Total encoder speedup with ext-inter: ~7.5%

- Confirm input coeff buffer is 16-byte aligned.
- sizeof() prefer variable name instead of type.
- Fix function name (Capital first letter then Pascal case).
- Long base class name uses a newline (with colon and 4 space indent).
- Remove a unnecessary reference function variable.
- Method declaration precedes variable declaration in class definition.

- 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.

- Tx_type: DCT_DCT, DCT_ADST, ADST_DCT, ADST_ADST.
- Encoder overall instruction count drops 2.91%.
- Decoder overall instruction count drops 1.01%.
- Add unit test to test bit-exact result against C.

Avoid accessing transform type that is not 2D-DCT if the transform
size is 64x64. This fixes an assert failure in this unit test.

In the tile-coding experiment,
1. In tile decoder, added 2 set control APIs:
VP10_SET_DECODE_TILE_ROW and VP10_SET_DECODE_TILE_COL. It allowed
users to set the range of decoding at frame level.
2. Added a unit test while tile-coding experiment is on. It tested
both tile encoder and decoder to make sure the encoded frame
can be decoded as a whole frame or as independent tiles.

Functions vp10_fwd_txfm2d_#x#_sse4_1 tested in this file

This change has no performance impact. It prepares the proper
function interface for better performance optimization.

- Tx_type: DCT_DCT, DCT_ADST, ADST_DCT, ADST_ADST.
- Update vp10_fht16x16_test.cc to do bit-exact test against
latest C version.
