Integrate intra mode mask speed feature with the mode_skip_mask
scheme. Move it outside the mode search loop in the
vp9_rd_pick_inter_mode_sb function.

This speed feature is used in real-time setting only. Remove the
related condition check in the rate-distortion optimization search
loop.

Refactor overlay frame speed-up related function. Make it unified
with the ref_frame_skip_mask system and Move it out of the mode
search loop.

This commit refactor the rate-distortion optimization search for
regular block sizes to remove the speed feature dependency on mode
search order.

This issue is found when the denoising mode is set to kDenoiserOnYUVAggressive.
Updated the C code to make it the same with SSE version.
I also changed several lines in VP9 denoiser for the code style.

don't bother decoding any further after receiving an earlier decode
error until a key/intra-only frame is encountered.

This commit fixes a bug related to skipping intra mode checking, by
using a separate variable to store the best prediction error from
inter mode. It avoids unintentionally overwriting intra mode
rate-distortion cost, and hence affecting other speed features.

Assigning selected reference frame pointer is done in the
encode_superblock function. No need to do this at the end of
rate-distortion optimization search.

This commit refactors the vp9_rd_pick_inter_mode_sb function to
remove the intra mode early termination dependency on the mode
search order.

This commit allows the encoder to find current best prediction mode
state using best_mbmode, instead of fetching from the static mode
search table via best_mode_index.

The use of use_lastframe_partitioning is totally removed in good-
quality encoding. Its usage in real-time encoding needs to be
evaluated to see if it can be removed too.
The Borg tests at speed 4 showed:
stdhd set: 0.220% psnr gain, 0.166% ssim gain;
derf set: 0.329% psnr gain, 0.476% ssim gain.
Speed test on selected clips showed 1.54% speedup.(Worst case:
pedestrian_area_1080p25.y4m, speed loss: 1.5%)

the code currently checks whether the allocation has been done instead
of allocating on the first frame.
since:

this change defers the allocation until the loop filter is used.

The speedup in rd_pick_partition() function makes it possible
to drop use_lastframe_partitioning feature. By doing that, we
achieve good PSNR gain with small speed loss. Also, this makes
encoding loop less complicated. The code cleanup patch will
follow.
Borg tests showed:
1. At speed 2,
stdhd set: 0.201% PSNR gain, 0.133% SSIM gain;
derf set: 0.262% PSNR gain, 0.276% SSIM gain.
2. At speed 3,
stdhd set: 0.139% PSNR gain, 0.109% SSIM gain;
derf set: 0.447% PSNR gain, 0.442% SSIM gain.
The average speed loss over selected test clips is within 1%
with the worst case of 4%.
