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

The change is just to keep the condition the same with VP8.

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

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%.

intra_super_block_yrd() and inter_super_block_yrd() are largely same,
this commit merges them into one to reduce code duplication.

From 3 to 2, which seems to be slightly positive on compression for
all test sets, also reduces encoding time by 2%-5%, varying on the
test clips.

This commit removes the special case for key frame, as transform size
decision is controlled by the appropriate speed feature for all lossy
coding modes: tx_size_search_method.
