ed36720b66 Do vertical loopfiltering in parallel 
This patch followed "Add filter_selectively_vert_row2 to enable
parallel loopfiltering" commit, and added x86 SSE2 optimization
to do 16-pixel filtering in parallel. For other optimizations
(neon and dspr2), current 16-pixel functions were done by calling
8-pixel functions twice, and real 16-pixel functions could be added
later.

Decoder speedup:
tulip clip:     2% speed gain;
old_town_cross: 1.2% speed gain;
bus:            2% speed gain.

64f728caef Do horizontal loopfiltering in parallel 
This patch followed "Rewrite filter_selectively_horiz for parallel
loopfiltering" commit, and added x86 SSE2 optimization to do
16-pixel filtering in parallel. Also, corrected the declaration
of aligned arrays. For 8-pixel-in-parallel case, improved the
calculation of the masks and filters. Updated the threshold loading
since the thresholds were already duplicated. Updated neon C functions
to call neon loopfilters twice.

Using tulip clip, tests showed it gave a ~1.5% decoder speed gain.

3a0602578e Giving consistent names to IDCT/IWHT functions. 
The idea is to have the following names for each transform size:

vp9_idct4x4_add
  vp9_idct4x4_1_add
  vp9_idct4x4_10_add
  vp9_idct4x4_16_add

vp9_idct8x8_add
  vp9_idct8x8_1_add
  vp9_idct8x8_10_add
  vp9_idct8x8_64_add

etc for 16x16, 32x32

The actual list of renames in this patch:

vp9_idct_add_lossless     -> vp9_iwht4x4_add
vp9_short_iwalsh4x4_add   -> vp9_iwht4x4_16_add
vp9_short_iwalsh4x4_1_add -> vp9_iwht4x4_1_add

5b1dc1515f Fix a bunch of TODO from vp9_short_idct32x32_add_neon. 
- full ASM version, no more C gateway file.
- integrate combine-add with last step of 2nd pass.
- remove a few push/pop pairs.
- some instruction reordering to hide latency.
