The function has evolved over time, now only calls vp9_rtcd(), so this
commit removes the function and changes to call vp9_rtcd() directly.

Optimizing 2 functions to process 32 elements in parallel instead of 16:
1. vp9_sub_pixel_avg_variance64x64
2. vp9_sub_pixel_avg_variance32x32
both of those function were calling vp9_sub_pixel_avg_variance16xh_ssse3
instead of calling that function, it calls vp9_sub_pixel_avg_variance32xh_avx2
that is written in avx2 and process 32 elements in parallel.
This Optimization gave 80% function level gain and 2% user level gain

different_ref_found is always equal to one (if calculated) because
ref_frame[0] != ref_frame[1] for each mi-block.

Adds a speed 8 to VP9 where only the nearestmv (0 mv) is searched.
This seems to be about the same speed as vp8 speed 5.
Adds a new speed feature to disable inter modes based on a mask for
each blocksize.
Adds code for having lower complexity motion search methods
in nonrd pick mode function, even though speed 7 still uses DIAMOND
search for now.
Also uses HEX search for speed 6 rather than FAST_HEX which improves
psnr by 0.56% without any noticeable speed drop (tested on gipsmotion).

For blocks at frame boundary, the selected block size sometimes needs
to be smaller than that was first given. This commit forces such block
size change only between square blocks, so as to avoid the potential
use case containing 32x16 + 16x8 + 16x8, for 1080p sequences.
Local test suggested no visible coding speed difference. Borg test
reveals no difference in terms of compression performance.

This commit checks if the motion vector associated with the current
mode has been computed in previous mode tests. If possible, skip the
redundant reference block generation and SAD calculation in the
non-RD mode decision process.
For test sequence pedestrian_area 1080p, the runtime goes from
24261 ms to 23770 ms. This does not change compression performance.
The speed-up is mostly around places with consistent motion.
