This CL contains two AVX2 optimized loop filter functions,
mb_lpf_horizontal_edge_w_avx2_8 and mb_lpf_horizontal_edge_w_avx2_16.

When only upper-left 8x8 area has non-zero dct coefficients, we
could skip 1D IDCT for 9th to 32th rows to save operations. This
function is called when eob <= 34.

For consistency with idct function names. Renames:
vp9_short_fdct4x4 -> vp9_fdct4x4
vp9_short_walsh4x4 -> vp9_fwht4x4

Just making fdct consistent with iht/idct/fht functions which all use
stride (# of elements) as input argument.

This patch fixed a bug that caused 32bit PIC build mismatch. The
stack pointer was modified after "GET_GOT". Loading left pointer
from a hard-coded position gave wrong result.

Commit "d207 intra prediction ssse3 using bytes" caused mismatch
while building 32bit PIC code. Disabled these SSSE3 functions
until we fix the bug.

We have two SSE2-optimized functions for idct4_1d:
vp9_idct4_1d_sse2 <-- removing this one
idct4_1d_sse2
vp9_idct4_1d_sse2 was used only by the following functions which already
have SSE2 optimized variants:
vp9_idct4x4_16_add_c -> vp9_idct4x4_16_add_see2
idct8_1d -> vp9_idct8x8_{16, 10, 1}_see2
vp9_short_iht4x4_add_c -> vp9_short_iht4x4_add_see2

To ensure fast encoding/decoding on devices without ssse3 support,
SSE2 optimization of sub-pixel filters was done. Test using 1080p
clip showed the decoder speeds were ~70fps with ssse3 filters, ~60fps
with sse2 filters, and ~15fps with c filters.

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
Change-Id: I6f43f7437c68dd30cdd05d72e213765578ed30b1
Moving functions from vp9_idct_blk to vp9_idct because these functions are
used from both encoder and decoder. Removing duplicated code from
vp9_encodemb.c and reusing existing functions.

byte version of ronalds d153 ssse3 optimizations for
4x4 and 8x8
(commit: fc91a2a112238a1aee568f3b840585de4e928fca)
Change-Id: Iec4426032311483f615fd9e0dceba3ee85ddebd7
We don't need these functions anymore. The only one which was actually
used is vp9_add_constant_residual_32x32. Addition of
vp9_short_idct32x32_1_add eliminates this single usage. SSE2 optimized
version of vp9_short_idct32x32_1_add will be added in the next patch set,
right now it is only C implementation. Now we have all idct functions
implemented in a consistent manner.
