Use the right return values - vadd_s64 returns int64x1_t, not
a normal int64_t.

This commit adds back sse2 or ssse3 optimized versio of a couple of
functions, fixes a ~10% performance regression.

The ARF frame should always be the same size as the
native resolution of the input frames.

It will be scaled to the required resolution at
encode time.

This commit makes the encoder to use non-zero mode threshold for
NEARESTMV modes. The runtime for test clips of speed 3 is reduced
by about 1%.

pedestrian 1080p 2000 kbps, 143239 ms -> 141989 ms
bus CIF 1000 kbps, 7835 ms -> 7749 ms

The compression performance change is about -0.02% for both derf
and stdhd.

If the partition block is skippable, which means no coefficients
for Y, U, and V planes, its skip flag is set to 1. No quality
change (verified by borg tests), and no noticeable speed change.

Merge "vp8/vp9: neon: msvc: move the 'ifdef _MSC_VER' bit to vpx_ports/mem.h.                      fix compiling warning."

Libvpx was memseting every external frame buffer before decode. This
was to work around a valgrind issue in our C loop filter. Most of
the time this was not needed and we have noticed some significant
performance loss on some platforms. Now we require the application to
zero out the buffers if it is using external frame buffers.

This commit enforces ARF validation check for compound inter modes.
It avoids potential access to ARF in the encoding process if it
is not allowed.

The valid reference frame check in sub8x8 rate-distortion
optimization search has been included in the ref_frame_skip_mask
scheme. This commit removes the later further validation checks
that are not in effect.

of best_mbmode in vp9_rd_pick_inter_mode_sub8x8.

Call to vp9_rc_get_second_pass_params() moved from
Pass2Encode() to earlier in vp9_get_compressed_data(),
to ensure that two pass stats and parameters are
available before decisions such as frame scaling.
