Update rdcost using the rd_mult in current block
This CL is a preparation for implementing hierarchical SSIM rdmult scaling.
There is very little impact on metrics and speed:

Fix calculations in GF only group case
- Fix the number of frames considered in calculation of
twopass active worst quality. For GF only group, frames
considered should be one less than baseline gf interval
accounting for the golden frame.
- Fix in calculation of normal_frames. As baseline gf
interval includes the golden frame, the number of
normal frames should be one less than baseline gf
interval.

Increase active best quality linearly
The ARF frames in last few gf intervals, would be
used as a reference by fewer ARF frames in the same
kf interval. Also, the ARF frames in the last GF
group would not be used as a reference in future.
Hence the active best quality for these ARF frames
is increased based on their temporal distance from
the next key frame.

Fix section intra rating for first ARF interval
The section intra rating used for the frames in the
first ARF interval was based on entire key frame
interval. However, for subsequent ARF intervals it was
based on that ARF interval. This discrepancy is fixed.
Reason for revert:
This has not been reproduced on hardware. There is a strange
libc bug which may account for the behavior on arm because
the environment qemu is using is somewhat old. See discussion
on the webm bug.
To work around the failures in the nightly test the jenkins
job has been switched to use the hardfloat compiler and qemu
environment. Even though this is the same version, it has
not shown the hanging behavior.

Fix tsan failure in webrtc test.
plane block size is used when computing model rd for uv.
However, it iterates thru sub-blocks based on tx size on uv planes
and plane block size could be bigger than that, which leads to reading
beyond tile boundary when the block is on it.

Cap arf boost in perceptual quality mode
When the perceptual AQ mode is enabled, cap the ARF boost to 2.5x
of the regular frame. This allows more consistent frame quality
across consecutive frames and sufficient bit rate allocation at
frame level for AQ mode.
Add a macro to to exclude VP9 specific assembly files from build if VP9
is not configured. This would otherwise cause a linking error for VP8
only builds.

Avoid two GF only groups just before a kf
Trap the case where we end up with two short GF only groups just
before a key frame. For example, if the KF is 22 frames away
we are better doing one ARF group of size 16 followed by a GF
only group of 6 than two GF only groups of size 11 (when
min_gf_interval is 12).
