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.

Allow building for targets which have NEON but not EDSP or MEDIA.
Set HAS_NEON flag for builds which have neon assembly but not
intrinsics.

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.
