This commit makes the dual filter experiment work with non-420
settings. It fixes unit test failure in EndToEndTestLarge.

Revisit the compression performance and complexity trade-off after
making the SIMD version of trellis optimizations. Before that,
reduce the transform-quantization function calls temporarily. This
would cause about 0.3% performance drop for lowres set.

1. Skip golden non-zeromv and newmv-last for bsize >= 16x16 if the
temporal variance obtained from choose_partitioning is very low.
2. Skip horz and vert INTRA mode for speed 8.
This change works best on the clips with little noise and with some
motion (e.g. gips_motion which has > 5% speed up). PSNR drop is 1.78%
on rtc test set, no obvious visual quality regression found.

This commit combines uniform quantizer with trellis based coefficient
level optimization. It improves the codebase compression performance:
lowres 0.8%
midres 1.0%
hdres 1.6%
Note that the current trellis optimization unit is using C code. This
will make the cost of the overall quantization process slower. A number
of optimizations will come up next.

This experiment implements non-uniform quantization where
the width of the bins increases gradually to more closely
match a laplacian distribution of the coeficcients.
Performance Gain:
derflr: 0.15%
hevcmr: 0.675%

Bring commits 575e81f and 3d6b8a6 to VP10. These changes predate
the creation of the active map cyclic refresh test.

Move initialization of a some new "twopass" values
to the function vp9_init_second_pass() and some other
small changes.
Remove #if GROUP_ADAPTIVE_MAXQ as this is always
enabled now.

On scene-cut detected frames (i.e., high_source_sad = 1), use
nonrd_pick_partition (over choose_part + select_part), as
the nonrd_pick partitioning is generally better.
Small positive increase in metrics on ytlive set (~0.5 - 1%).
Negligle overall speed decrease, as its only used on scene-cut frames.
Only affects 1 pass vbr mode, speed = 5.

The assumption doesn't hold true in the current codebase. Remove
this speed feature to simplify the codebase.

The inter prediction residual can undergo different transform types
during the rate-distortion optimization search. The assumption used
in this speed feature no longer holds true. This commit removes the
related code to clean up the codebase and clear out unit test
failure in higher speed setting.
