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

vp9_idct_add            -> vp9_idct4x4_add
vp9_short_idct4x4_add   -> vp9_idct4x4_16_add
vp9_short_idct4x4_1_add -> vp9_idct4x4_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.

vp9_short_idct10_16x16_add is used to handle the block that only have valid data
at top left 4x4 block. All the other datas are 0. So we could cut many
unnecessary calculations in order to save instructions.

5e2e78d024 vp9: neon: optimise loads in horiz convolve functions 
Loading to single lanes in multiple registers is expensive since
it requires a read and write of each register which saturates
the register file access.  Loading to single registers followed
by a separate transpose reduces this pressure.
