This rebase is a better implementation of the previous ones.
Modifications are done to reduce the total clock cycle.

Commit a4a5a210 enabled lossless coding, but the commit incorrectly
disabled the usage of skip in encoder even when skip should be used.
This commit make sure that skip is enabled even in lossless mode.

Since they used in encoder only. This commit also re-order includes
for the files that include vp9_extend.h

Explicitly constrain the upper limit of motion search range (in the
unit of full pixel) to be [-1023, +1023]. It is intended to control
the effective motion search range for 4K sequences.

This patch followed "Rewrite filter_selectively_horiz for parallel
loopfiltering" commit, and added x86 SSE2 optimization to do
16-pixel filtering in parallel. Also, corrected the declaration
of aligned arrays. For 8-pixel-in-parallel case, improved the
calculation of the masks and filters. Updated the threshold loading
since the thresholds were already duplicated. Updated neon C functions
to call neon loopfilters twice.
Using tulip clip, tests showed it gave a ~1.5% decoder speed gain.

on arm until we implenment real vp9_idct32x32_34_add_neon.
This issue is due to commit 47665452f0
Merge "Add 32x32 idct function for eob<=34 case".

Simplifies the code by implementing band mapping with static arrays.
A lot of the code complexity introduced in a previous patch
disappears.

The switch to the rate-correction damping factor
in https://gerrit.chromium.org/gerrit/#/c/67536/ was not conditioned on CBR mode.

The step that sums three input samples could potentially cause the
intermediate result go beyond 16 bit limit, when operating as the
second 1-D transform. This commit fixes the issue.
