3d655805f2 Use same intra prediction for all block size
The commmit changed to use same intra prediction function for all
block sizes.

Some details on the changes:
1. All directional modes except DC/TM/V/H now have built-in filtering
for all pixels with filter taps either (1, 2, 1)/4 or (1, 1)/2.
2. Above edge get automatic extended to double width (bw*2), which
makes a lot of the prediciton mode computation simpler.
3. Same intra prediction function is called with different size
for i4x4_pred and all other larger size.

Overall, the change helped keyframe only coding for both cif size
and std-hd size test sets by .5% consistently on all encodings.
For normal coding with single/auto key frame, the change now also
is consistently net positive for all encodings. The overall gains
is about .15% on std-hd set.

7c5eb6d5da Fix mi_row argument to update_stats().
This doesn't change output, because the argument isn't actually used
ATM. However, we should fix it for consistency.

3ac3c4695c Immigrate tokenize_mb into tokenize_sb
Unify the tokenize_ function and enable configurable block size for
superblock 8x8. We are immigrating the functionalities of
macroblock handles into superblock ones, and eventually will remove
encode_mb and decode_mb. To be continued on detokenize_ module.

040eeed9d0 Turning model based reverse update on for coefs
Turns model based reverse updates on for coefficients in an
effort to reduce the memory requirement for counters.

With this patch the counters needed will be reduced by about
75% since only 3 counts are needed instead of 12.

The impact in performance is:
derf300: -0.252%
stdhd250: -0.046%

However retraining should alleviate some of the drop in
performance.

34324a98e7 Restore vp9_asm_enc_offsets.c
The previous commit 15255ee "Move dequant from BLOCKD to per-plane MACROBLOCKD"
removed the vp9_asm_enc_offsets.c file, but didn't update the various secondary
build systems that special case these files. Restore it for now, to ensure any
in-progress changes and builds continue working, to allow time to more carefully
coordinate removal of these files.
