No need to do avoid shortcuts when all we are testing is the superframe
syntax. Decreases the run time up the VP10 version of the test from 22
seconds to 3 seconds on my machine.

- 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%

Change only affects 1 pass, vbr, speed = 5 (real-time mode).
Some improvement for high motion content.
AvgPSNR/SSIM metrics for ytlive set all up, on average ~2%,
some clips (high motion ones) up 4/5%.
Encoder speed down: on mynintendo_x1.1280_720.y4m: 47fps -> 44fps.

Skip checking obmc when regular inter predictor is not so good (the
rd-cost for Y residual is greater than the total rd of the best mode
so far.)
Performance change compared to full rd search:
+0.006% lowres, -0.056% midres
Encoding time :
1.14X baseline (was 1.42X)

the vpx_decoder layer guarantees that when called directly this won't
receive NULL data and the reuse via decode() is protected by a NULL data
check and 0 size check (NULL data and non-zero data size is protected by
the vpx_decoder layer).

After porting tile coding from VP9 to VP10, some performance
degradation was seen because of the difference between VP9 and
Vp10 baseline. This patch disabled some features in VP10 while
tile coding is turned on. Also, an encoder control API was added
back for this use case.

Skip filtered intra modes search in inter frame when DC mode is
worse than the best mode so far.
With ext-intra enabled, the overall speed is increased by 20~40%;
performance drop is 0.03% on lowres and 0.05% on midres.

- Added function fidtx4_sse2().
- Turned on vp10_fht4x4_sse2() for these tx types.
- Updated 4x4 unit test for speed/accuracy.
- 4x4 Unit test passed.
- Running 20K times with random numbers for tx type from
V_DCT to H_FLIPADST, SSE2 against C, speed improves ~46%.

If configured with --enable-ext-tile, the codec uses an alternative
tile coding syntax in the bitstream. Changes include::
- The maximum number of tile rows and columns is extended to 1024
each.
- The minimum tile width/height is 64 pixels (1 superblock).
- A tile copy mode is added where a tile directly reuse the coded
data of a previous tile
- The meaning of the tile-columns and tile-rows codec parameters are
overloaded to mean tile-width and tile-height in units of 64
pixels.
- All tiles should now be independent, including rows within the
same columns, so large scale parallel, or independent decoding is
possible.
- vpxdec also gained the options to decode only a particular tile,
tile row, or tile column.
Changes without --enable-ext-tile:
- All tiles should now be independent, including rows within the
same columns, so large scale parallel, or independent decoding is
possible.
- vpxenc default tile configuration changed to use 1 tile column.

The mv is clamped in dec_find_mv_refs() to a smaller region
than the clamp in dec_find_best_ref_mvs(). See clamp_mv_ref
and clamp_mv2.

- Use Makefile to control the build for highbd_fwd_txfm_sse4.c.
- Fixed hybrid transform (HT) types due to recent update.
- Added new unit test cases for highbd HT.

This commit separates the predicted motion vector from the nearestmv
motion vector in the coding process for both regular and sub8x8
block sizes.

- Setup function vp10_highbd_fht4x4_sse4_1 for highbd SSE4.1
intrinsics optimization.
- Wrote SSE4.1 functions: load_buffer_4x4(), write_buffer_4x4(),
and fdct4x4_sse4_1().
- Used logic right shift to avoid coeff memory write/read.
- Turned on vp10_highbd_fht4x4_sse4_1 for DCT_DCT mode only.
- Improved overall encoding performance >2.3% for 50 frames
sequence, park_joy_1080p_12.y4m, in which, --input-bit-depth=12,
--bit-depth=12, 50 frames.
- Unit test passed.
