When a reference frame type is not in the frame buffer, the mode
search threshold will be set to INT_MAX, so as to effectively
turn off the mode entries in the rate-distortion optimization loop
that involves this reference frame type. This operation is now
integrated in the ref_frame_skip_mask scheme. This commit hence
removes the redundant mode search threshold setting.

This commit unifies the reference frame control in the rate-
distortion optimization search loop of sub8x8 block size to remove
the control dependency on mode search order.

The variable best_inter_rd is effectively not in use in the rate-
distortion mode search loops of both regular block sizes and sub8x8
block sizes.

The speed feature that skips compound inter prediction modes was
subsumed by other speed features and effectively was not in use.
This commit removes it.

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 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 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%.

The rate costs calculated for inter modes are not precise in some
cases, which causes NEWMV is chosen instead of NEARESTMV, NEARMV,
and ZEROMV. This patch added checks for these cases, and corrected
the mode decisions.
Borg tests at speed 3 showed:
1. stdhd set: 0.102% PSNR gain and 0.088% SSIM gain.
2. derf set: 0.147% PSNR gain and 0.132% SSIM gain.
No speed change.

Removed functions:
* vp9_post_proc_down_and_across_mmx
* vp9_mbpost_proc_down_mmx
* vp9_plane_add_noise_mmx
They all have sse2 equivalent.
