This reverts commit 89a1efa4c436c58c101c8b3de866e3014be7d77a.
This causes a segfault when decoding vp8, in both 32 and 64-bit

use CONFIG_VP[89] to protect white-box tests and drop redundant
uses of CONFIG_VP9 in variable assignments within that block

For non-rd variance partition: Adjust variance threhsold based
on noise level estimate. This change allows the adjustment to be
updated more frequently.

Relocate the function from SSSE3 to SSE2, Unroll loop from 8 to 4,
and reduce mem access to left.
Speed up by >20% in ./test_intra_pred_speed.

The range_check is not used because the bit range
in fdct# is not correct. Since we are going to merge in a new version
of fdct# from nextgenv2, we won't fix the incorrect bit range now.

For low resolutions, whem 4x4downsample is used for variance,
use the same force split (that is used for 8x8downsample) for 16x16 blocks.
No change in metrics. Small improvement visually.

the loop filter level is transmitted as 6-bits + sign so needs to be clamped in
the delta + absolute case.

1) Add facade to quantize b/fp/dc version so that their interface
are the same.
2) Merge vp10_xform_quant b/fp/dc version to one function so that
the code flow in encodemb.c is clear

This is so we may update level at any time (e.g., to be used
for setting thresholds in variance-based partition).

Estimate angle histogram using gradient analysis, then skip those
angles that are unlikely to be chosen.
On ext-intra experiment, turning off filter-intra modes:
for all-key-frame setting, computation overhead is reduced
by about 40%, coding gain dropped from +2.08% to +1.96% (derflr);
with kf-max-dist=150, computation overhead is reduced
by about 60%, coding gain dropped from +0.58% to +0.49% (derflr).

For non-rd variance partition: only allow minmax computation
(which currently has no arm-neon optimization) for speeds < 8.
Performance loss is small: On RTC set with speed 8, few clips lose ~2/3%,
average loss is < 1%.
