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

Speed 4 still does not give a big gain over speed 3.
This just cleans it up a little from the last patch and comments
out features that do not seem to be giving much benefit.

Allow selective masking of individual split modes rather than
just a single on / off flag.
For speed 2 recovers the large speed loss seen for some derf
clips in change Ie6bdfa0a370148dd60bd800961077f7e97e67dd4
and a small quality gain.
For speed 1 10 % speed increase observed locally on some derf clips
for minimal quality change.

Moving INTERPOLATIONFILTERTYPE enum and subpix_fn_table struct to
vp9_filter.h. Adding convenient typedef for subpel kernels.
Function vp9_setup_interp_filters() besides setting xd->subpix.filter_x &
xd->subpix.filter_y has a side effect of also setting scale factors. This
is not required inside decode_modes_b() because scale factors have been
already set by set_ref() calls. That's why replacing
vp9_setup_interp_filters() call with newly created vp9_get_filter_kernel()
call. The behavior of vp9_setup_interp_filters() is unchanged (it
is used from the encoder).

This commit removes the redundant second reference frame check in
the rate-distortion optimization loop for sub8x8 blocks.

This commit defines b_mode_info as a struct type. This will allow
us to further remove the use of PARTITION_INFO in the encoding process.

This commit separates the rate-distortion optimization loop of
superblocks from that of sub8x8 blocks. This allows better design
rate-distortion optimization search loop for each setting. It also
removes the use of SPLITMV and I4X4_PRED therein.
No performance change in speed 0 settings. For bus@CIF at 2000kbps,
the speed 1 runtime goes from 48009ms to 43894ms (about 10% faster).
The overall compression performance on derf changed by -0.021%.
Speed 2 runtime goes from 27114ms to 28700ms (6% slower), while the
overall coding efficiency goes up by 1.629% for derf, 1.236% for yt.
