C version and sse2 version, and off by default.
For the test clip used, the sse2 performance improved by ~5.6%

Allow for an option to selectively apply the deblocking loop filter to the denoised
raw block, based on the denoised state (no-filter, filter with zero motion, or filter with non-zero motion)
of the current block and its upper and left denoised block.
This helps to reduce some blocking artifacts from the motion-compensated denoising.

When this compiler flag is enabled, the encoder will write a denoised,
uncompressed, version of the input to denoised.yuv.

By enabling the OUTPUT_YUV_SRC compiler flag, the encoder will write the raw
input to bd.yuv.
The functionality was mostly implemented, but in its previous state did not
compile.

Now match the "C" version of "Fix to reduce block
artifacts from vp8 temporal denoiser."

In the current logic, if the sse for zero motion is smaller
than the sse for new_mv (i.e., best_sse), we may still end up
using the non-zero mv for denoising (if the magnitude of new_mv is above threshold).
This can happen for very noisy content, and can lead to artifacts.
This change ensures that we always use zero_mv (over new_mv) for
denoisng if sse_zero_mv <= best_sse.

If the denoiser filter causes too big a change in the absolute pixel difference
(between source and denoised signal), the block is not denoised, which can cause
visual block artifacts. This change applies a second adjustment to the temporal filter
to effectively allow for a (weaker) denoising for such blocks (which can keep
the absolute differnence within the tolerance range in most cases).
This helps to reduce some of the block artifacts from the denoising.
The additional cost of re-applying the filter to this set of blocks is low,
as the percentage of blocks per frame (with too big a change in absolute pixel difference)
is typically small, 2-5%.

Renames all x86_64 specific assembly files to consistently
end in _x86_64.asm. This will be useful for build systems to
handle these files differently.
All new 64-bit specific assembly files should use the new
naming convention.

Failed
This patch did not address all the assembly issues
some of the vp8 assembly counts on 5 arguments being passed in to this function:
one example : vp8_sad8x16_wmt
Please address or split this into vp9 and vp8 patches.

As a side-effect, the max_sad check is removed from the
C-implementation of VP8, for consistency with VP9, and to
ensure that the SAD tests common to VP8/VP9 pass.
That will make the VP8 C implementation of sad a little slower
but given that is rarely used in practice, the impact will be
minimal.

Added macro to conditionally compile some of the
post-processing functions only when CONFIG_POSTPROC
is defined.
This was causing the build for the generic-gnu target
to fail.

The rounding of the ARNR filter output prior to
normalization by the filter strength was incorrect
when strength = 0.
In this case 1 << (strength - 1) would not create the
required rounding of 0, rather it would outrange. This
patch fixes this issue.

This patch did a cleanup following the commit "Save NEON registers
in VP8 NEON functions". The pushing/poping of callee-saved NEON
registers was moved into individual NEON functions. Therefore,
we don't need to save those registers at the beginning of codec.
The related code was removed.

The recent compiler can generate optimized code that uses NEON registers
for various operations besides floating-point operations. Therefore,
only saving callee-saved registers d8 - d15 at the beginning of the
encoder/decoder is not enough anymore. This patch added register saving
code in VP8 NEON functions that use those registers.
