vpx_convolve8_avg works by first running a normal horizontal filter then a
vertical filter averages at the end.
The added vpx_convolve8_avg_avx2 calls pre-existing AVX2 code for the
horizontal step.
vpx_convolve8_avg_vert_avx2 is also added, but only uses ssse3 code.

This reverts commit 9311ef18b4.
Reason for revert:
Notice small regression in some clips.
Will revisit in another change.

For 1 pass vbr: increase min_thresh slightly, and also add
condition on golden/arf update for using full nonrd_pick_partition.
Reduces possible false detection for scene cut detection.
Neutral/small change in metrics or speed for speed 5.
Change-Id: I388f4d9a56e3cc763e0148338c1bc0381e58ad76
Small/neutral change in metrics or speed for ytlive.
Some improvement in quality on frames with big content change.
Change-Id: Ib3b0703a5f28ea6710e90324436e27598ab7384d
Lower SAD threshold to select non_rd pickmode partition
at superblock level more often.
Small gain in metrics, small/negligible decrease in speed.
Change-Id: I0f728236b91a604e4ca7e02039adc54d5985c4dc
For 1 pass vbr speed >= 6: when REFERENCE_PARTITION is selected,
avoid doing the full nonrd_pickmode based partition.
No change in overall metrics or speed.
Reduces encode times on scene cuts by 10-20%.
Change-Id: I0310b1610cc1c83793a509e0a9059840e8f18308
For 1 pass vbr mode:
On no-show_frame/ARF: instead of skipping alt_ref_frame
completely in mode testing, allow for checking (0, 0) on alt_ref.
Small gain in metrics, ~0.18%, no change in speed.
Change-Id: I32a3c24faca64ab70dd5091071a0dc301db7dd1e
For 1 pass vbr: when significant content/scene change is detected
(high_source_sad = 1) reduce/turnoff the additional qdelta on the
active_worst_quality. This helps somewhat to reduce the occurrence
of large frame sizes and large encode times.
Allow it only when use_altef_onepass is enabled.
Neutral/no change on metrics.

For speed 6 real-time mode: use adapt_partition
on ARF frame instead of REFERENCE_PARTITION (which is slower).
This requires enabling compute_source_sad_onepass for no-show_frames.
Speedup of ~3-5% on some clips that heavily use ARF,
small loss (~0.2%) in quality on ytlive set.
Change-Id: Ib50acc97df06458244a6ac55d2bd882c30012536
Speed comparing with the one calling vpx_scaled_2d_neon()
~1.7 x in general
~2.8x for BILINEAR filter
BUG=webm:1419
Change-Id: I8f0a54c2013e61ea086033010f97c19ecf47c7c6
Scale 3x3 block instead of 16x16 block in each loop. Disabled by
default.
Benefits:
1. Reduced number of different phase_scaler from 16 to 3.
Optimization code will be smaller and faster.
2. Maximum phase_scaler drifting will be reduced from 5/16 to 1/24.
(The drifting is 1/(3*16) in each step.)

For real-time mode. Move the switch to fixed partition
for is_src_frame_alt_ref so all speeds may use it
if use_altref_onepass is set.
Improves metrics by ~2% for ytlive set at speed 4
(where use_altref_onepass is currently used).
Change-Id: I033240386598c9dbd0364da89ccbcca64bc663ee
Only has effect when sf->use_altref_onepass is enabled,
as in that case scene detection is skipped for non-show frame
and so high_source_sad does not get reset to 0.
No change in metrics or speed.
Change-Id: I421f066d239341449c18826089e1810b9fc5967f
Add stats for past ARF usage, and use it to disable
ARF usage based on some conditions.
Overall improvement on ytlive set, reduces the regression
on the problem clips for this feature.
Only affects when sf->use_altref_onepass is enabled
(currently off by default).

This reverts commit 535b7b915a.
This is actually used in CBR to reset the rate control if high source sad is detected.

Scene detection is used for VBR mode and for screen_content mode.
It was also enabled for CBR mode via the speed condition,
but currently the analysis in the scene detection is not used
in CRB mode (similar computations are done locally at superblock level
when the source_sad feature is enabled).
For 1 pass code.
No change in behavior. Small speed gain, ~0.5%.
