Set speed features before running frame encoding. This avoids
redundant RD threshold calculation in key frame coding.

* Remove all non-DC intra modes for BLOCK_32x32 and up
* Remove all intra modes for blocks bigger than BLOCK_32x32
* Remove ZEROMV for BLOCK_32x32 and up
* Only consider NEARESTMV for blocks bigger than BLOCK_32x32

The core motion estimation fucntions all return sad now consistently.
The only exception is vp9_full_pixel_diamond(), however the core diamond
and refining search routines called from vp9_full_pixel_diamond() also
return SAD. If variance of pred error + mv cost is desired it must be
calculated explicitly outside these functions. For very fast encoding,
hopefully this will eliminate some redundant computations.
Also suggests reimplementing FAST_HEX with the vp9_pattern_search
framework. It is not exactly the same as the existing FAST_HEX, but
performance is slightly better and speed is very similar. Enables
removing a lot of duplicate code.

* speed improvment of 30 percent achieved
* multiplies and adds remain the same
* non-arithmetic instructions minimized by hand, by:
-expanding 2 pass loop
-removing irrelivant "shuffles"
-combining last two rounding steps
* further improvments may be possible

This patch adds a new speed feature which doesn't do the rather
expensive entropy context lookup or save to the table, while
doing costing.
The speed up on desktop36p.y4m is around 10% other clips much less.
On the RTC test set this was + 1% in overall datarate.

This gets more accurate mode hit stats. It's also the first step to
handling ZEROMV not being allowed more intelligently.

intra_y_mode_mask is already enforced for the sub8x8 case.
intra_uv_mode_mask is already enforced for all sizes.
