Removed functions:
* vp9_post_proc_down_and_across_mmx
* vp9_mbpost_proc_down_mmx
* vp9_plane_add_noise_mmx
They all have sse2 equivalent.

vp9_variance_sse2.c contains a mix of intrinsics and references to
assembly which uses x86inc.asm; it's conditionally included as a result.

make bifilter4_coeff[][] uint8_t, no values exceed this range and
they're loaded with vdup_n_u8().

allocations within vp9_alloc_context_buffers() rely on mi_rows/mi_cols
individually, use those to determine whether to realloc rather than
stride and stride * rows. this fixes a crash with some fuzzed files for
invalid accesses into last_frame_seg_map and above_context.

proceeding using a corrupt (incompletely decoded) frame reference may
lead to incorrect assumptions about allocation sizes leading to a crash.

This commit turns on adaptive motion search for ARF coding, in
addition to other normal inter frame coding. It improves the
average compression efficiency:
stdhd 0.1%
derf 0.04%
For the test sequences, the speed 3 runtime is reduced:
pedestrian 1080p 2000 kbps, 149932 ms -> 144580 ms, (3.3% speed-up)
bus CIF 1000 kbps, 8050 ms -> 7895 ms, (1.9%)
highway CIF 100 bkps, 45033 ms -> 44078 ms, (2.2%)

This is to keep the same with VP8 denoiser.
If motion magnitude is small,
make denoiser more aggressive.

Calling Reset(int) method instead of overloaded operator()(int).
Adding underscore at the end of class member name.

When the first try of denoising turns out to be too much,
we will use a softer filter by adopting an adjustment to
make the result closer to original pixel (as in VP8 denoiser).
The old code made the adjustment in the wrong direction.

Use the right return values - vget_low_s64 returns int64x1_t, not
a normal int64_t.
Also make __builtin_prefetch a no-op on MSVC for this file.

This commit allows the encoder to store outcomes of single reference
frame modes and compares them to decide if the inter prediction
filter, forward transform, and quantization can be skipped.
The compression performance of speed 3 is down
derf -0.364%
stdhd -0.198%
For test sequences, the speed 3 runtime is reduced
highway CIF 100 kbps, 51976 ms -> 45033 ms, 13% speed-up
stockholm 720p 1000 kbps, 71826 ms -> 67838 ms, 5.5% speed-up

vp8_build_intra_predictors_mbuv_s().
This patch replaces the assembly version with an intrinsic
version.
On a Nexus 7, vpxenc (in realtime mode, speed -12)
reported a performance improvement of ~2.6%.
