For at least some of the implementations of sdx8f, such as
vpx_sad4x4x8_sse4_1, aligned moves are used to move the results into the
array.

block_variance: This operates on 8x8s and would be safe with a int32 *
int32 to uint32 multiply, but this is potentially unsafe for 12-bit
input. Unfortunately the code already segfaults on 12-bit input:

calculate_variance: This operates on up to a 32x32 of 8x8s and can
overflow even with 8-bit input (log2((256*32*32)**2) == 36).

- Tx_type: DCT_DCT, DCT_ADST, ADST_DCT, ADST_ADST.
- Update vp10_fht16x16_test.cc to do bit-exact test against
latest C version.
- HBD encoder speed improves ~1.8%.

This commit fixes the compiler error in high bit-depth inter
predictor when dual filter type experiment is turned on.

This change makes the c match the assembly and removes the todo's
associated with getting this to work.

This patch changes the encoder only for the ext-refs experiment. For
each newly coded frame to refresh the LAST_FRAME, the decoder is
notified that the LAST4_FRAME is to be refreshed, and read out the
updated reference frame buffer vitural indexes for the next coded
frame in a way that:
LAST4_FRAME => LAST_FRAME,
LAST_FRAME => LAST2_FRAME,
LAST2_FRAME => LAST3_FRAME, and
LAST3_FRAME => LAST4_FRAME.
Compared against the original ext-refs experiment in TOT, a small gain
is achieved in overall PSNR:
lowres Avg: -0.154
lowres BDRate: -0.044

Make the bit-stream level support per direction filter type coding
for motion compensated reference.

These implementations rely on casting the pointers to load the data.
Clang implemented optimizations which automatically add alignment hints
to such loads. The 4x4 filters do not guarantee the necessary alignment
so the resulting assembly is broken.

* changes:
vp9_frame_scale_ssse3.c: make 2 functions static
vp9_pickmode.c: make function static
vp9_noise_estimate.c: make function static
vp9_aq_360.c: add missing include
vp9_idct_intrin_sse2: add missing vp9_rtcd.h include
vpx_dsp/*.[hc]: add missing vpx_dsp_rtcd.h include
The word 'pick' is usually used in functions that make decisions where
the bitstream allows multiple legal choices, and not to limit the
bitstream format itself.

This experiment will implement the use of a backward prediction
reference without temporal filtering. No overlay frame will be
transmitted, instead, the flag of show_existing_frame will be turned
on.
