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:
4f27202 vp9: fix crash in mt loopfilter w/corrupt file
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%.

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.

vp9_variance_sse2.c contains a mix of intrinsics and references to
assembly which uses x86inc.asm; it's conditionally included as a result.

allocations within vp9_alloc_context_buffers() rely on mi_rows/mi_cols
individually, use those to determine whether to realloc rather than
stride and stride * rows. this fixes a crash with some fuzzed files for
invalid accesses into last_frame_seg_map and above_context.

proceeding using a corrupt (incompletely decoded) frame reference may
lead to incorrect assumptions about allocation sizes leading to a crash.

This commit turns on adaptive motion search for ARF coding, in
addition to other normal inter frame coding. It improves the
average compression efficiency:
stdhd 0.1%
derf 0.04%
For the test sequences, the speed 3 runtime is reduced:
pedestrian 1080p 2000 kbps, 149932 ms -> 144580 ms, (3.3% speed-up)
bus CIF 1000 kbps, 8050 ms -> 7895 ms, (1.9%)
highway CIF 100 bkps, 45033 ms -> 44078 ms, (2.2%)

This is to keep the same with VP8 denoiser.
If motion magnitude is small,
make denoiser more aggressive.
