Removed inline for GP load-store in case of (__mips_isa_rev >= 6)
Created one define LD_V for vector load and ST_V for vector store

Also add column headings so that the output can still be parsed if the
set of headers changes later.

This reverts commit 8c42237bb200253931c49e2c530838f3a877dd65.
Because ssse3 code is used for the reference, the qcoeff and dqcoeff
reference buffers must be aligned.

Scale 3x3 block instead of 16x16 block in each loop.
Benefits:
1. Reduced number of different phase_scaler from 16 to 3. Optimization code
will be smaller and faster.
2. The maximum phase_scaler drifting will be reduced from 5/16 to 1/24.
(The drifting is 1/(3*16) in each step.)

The intra mode rd penalty was implemented as a rate penalty.
Code was added to scale the penalty according to block size but
this was not done correctly for the SB level or sub 8x8.
The code did a weird double scaling in regard to bit depth that
has been removed. Given that it is a rate penalty the bit depth
should not matter.
This bug fix improves average metrics on our standard test
sets by about 0.1%

Move class VpxScaleBase to new file test/vpx_scale_test.h.
Add new file test/vp9_scale_test.cc with ScaleFrameTest.

This header doesn't build on g++ v6 as it's a C and not C++ header
(_Atomic is not a keyword in C++11). Since the C and C++ invocations
cannot be guaranteed to point to the same underlying atomic_int
implementation, remove support for them and use compiler intrinsics
instead.

Makes main thread wait for the filter level to be picked to avoid a race
between the LPF thread and update_reference_frames(). This also
re-enables the failing tests under thread_sanitizer where this data race
was detected.

Fixes issue on iPad Pro 10.5 (and probably other places) where threads
are not properly synchronized. On x86 this data race was benign as load
and store instructions are atomic, they were being atomic in practice as
the program hasn't been observed to be miscompiled.
Such guarantees are not made outside x86, and real problems manifested
where libvpx reliably reproduced a broken bitstream for even just the
initial keyframe. This was detected in WebRTC where this device started
using multithreading (as its CPU count is higher than earlier devices,
where the problem did not manifest as single-threading was used in
practice).
This issue was not detected under thread-sanitizer bots as mutexes were
conditionally used under this platform to simulate the protected read
and write semantics that were in practice provided on x86 platforms.
This change also removes several mutexes, so encoder/decoder state is
lighter-weight after this change and we do not need to initialize so
many mutexes (this was done even on non-thread-sanitizer platforms where
they were unused).

Neutral on rtc set for speed 8. Neutral on ytlive for speed 5.
Saves some computation cycles but no speed gain observed on Pixel.

This reverts commit df9ce12259a4e866feeb580d2e0cf9648f60d3b5.
Reason for revert:
Re-enabled tests still fail tsan in high bitdepth.

> Re-enable disabled tests under TSan.
>
> These tests point to an already-fixed bug, this should no longer have a
