This was ported from the greedy version in AV1, written by Dake He
(dkhe@google.com).
See:
https://aomedia.googlesource.com/aom/+/master/av1/encoder/encodemb.c#137

Greedy version is disabled by default, but can be picked by setting
USE_GREEDY_OPTIMIZE_B to 1.
To be enabled by default later.

This is both faster and better in terms of compression.

Compression Improvement:
------------------------
lowres: -0.119
midres: -0.064
hdres:  -0.405

Speed Improvement:
------------------
(Based on encode time of 3 videos of different difficulties at
3 different target bitrates)
With --cpu-used=0: 0.38% to 5.55% faster
With --cpu-used=1: 0.24% to 2.79% faster
With --cpu-used=2: 0.29% to 1.46% faster

Set subpel prune_evenmore only for non_reference frames,
instead of all TL > 0 frames. Gain some quality back at
cost of small speed loss (~1-2%).

Change only effects SVC encoding at speed >= 7.

x86 simd register operations generally prefer and may require 16 byte
alignment.

the check for error correction being disabled was overriding the data
length checks. this avoids returning incorrect information (width /
height) for the decoded frame which could result in inconsistent sizes
returned in to an application causing it to read beyond the bounds of
the frame allocation.

min_gf_interval should be no less than min_altref_distance + 1,
as the encoder may produce bitstream with alt-ref distance being
min_gf_interval - 1.

Roughly 2x speedup. Since the only change for HBD is to store(), the
improvement appears to hold there as well.

* changes:
  buffer.h: add num_elements_
  buffer.h: zero-init all values
  buffer.h: use size_t

Enable simple_block_yrd for temporal enhancement layers (TL > 0).
And remove block size condiiton for SVC mode.
Only affects speed >= 7 SVC.

Speedup ~3-4%.
avgPSNR regression on RTC for (3 spatial, 3 temporal) layers: ~1%.
