INLINE is used quite widely in vp9, this change improves performance
1-2% on most modern platforms.

Assembly tests should clear system state, as we have no
expectation of proper system state in between test runs..

This commit fixes a bug in the PICK_MODE_CONTEXT index for
horizontal partition case. The compression performance change
is less than 0.01% level, since most blocks are selected to
use square block size in RTC coding mode.

This commit explicitly uses the bit shift operation instead of
division for computing block variance.

The 8x8 DCT uses a fast version whenever possible.
There was a mistake in the checking code which
meant sometimes the fast version was used when it
was not safe to do so.

(cherry picked from commit fd05fb0c21e253b4d6f92d7e0b752850ff8ab188)
This commit refactors the choose_partitioning function. It removes
redundant memset calls and makes the encoder to calculate
variance value per block only when it is needed. It reduces the
average runtime cost of choose_partitioning by 60%. Overall it
reduces speed -6 runtime by 2-5%.

It is the first version of MFQE in VP9. There are a few TODOs included
in this version.
Usage: Add flag --enable-vp9-postproc to config the project.
In decoder, use flag --mfqe in the command line to enable
MFQE in postproc.
Note: Need to have key frame with low quality to see the effect of this
new patch. In my experiment, I fixed the qindex to 200 in key frame.

Replace error_resilient flag with use_prev_frame_mvs in
vp9_pick_inter_mode reference motion vector search selection.
This effectively turns off the simplified ref mv search in the
settings of frame resizing, even if error-resilient mode is off.

Update the frame motion vector only if previous frame motion vector
is needed for next frame reference motion vector.

The warning only happens in VP9 encoder's first pass due to src_mi
is not set up yet. But it will not fail the encoder as left_mi and
above_mi are not used in the first_pass and they will be set up again
in the second pass.

This allows us to track decode speed for new encodes so that we catch
problems like an encode change that makes decode really slow.

This commit enables the use of sub8x8 blocks in RTC key frame
encoding. It requires the block size to be preset and will decide
the coding mode and encode the bit-stream.

Rename set_modeinfo_offsets as set_mode_info_offsets, to be more
consistent with naming convention.

The later encoding process will take the top-left block's
mode_info for pre-determined block size.
