The superres scale was accidentally only sent if the current frame was
a key frame or if the current resolution was not used by any of the
reference frames. This patch separates the superres scale from the
current resolution to simplify its coding and makes sure that it is
written for every frame.

Since wedge is not used for blocks > 32x32, skew the
initial probabilities to make the wedge probability
as small as possible.

* Calculate sx4, sy4 by truncation instead of rounding
* Move some repeated calculations out of the filter loop

This is expected to have a roughly neutral effect on BDRATE.
The speedup of each filter (SSE2, lowbd SSSE3, highbd SSSE3) is
7-10%, for a total speedup of 14-18% when considered together
with patches f7a5ee53 and 14b8112b.

We no longer support armv6 and the corresponding
optimized source files have been removed. This
commit removes support for the target and its
media instruction set extensions from the build
system as well.

Once armv6 jobs are removed from the integration
config we can start rejecting --enable/disable-media.

Also reject --enable-edsp.

Adds handling needed for the pre-encode downscaling for superres
encoding. Makes use of the existing resizing functionality, just
adjusting the target resolution after the resize logic and before the
resize has actually occurred.

Since the upscaling portion of superres is not yet implemented, superres
scaling is not yet allowed to trigger. The numerator is set to be equal
to the denominator and the superres_pending flag is not set.

Libvpx dropped armv6 support sometime after the aom fork.

We don't intend to support this platform, which is likely
too slow in any case. Remove the assembly and intrinsics
optimized routines, their tests, cpu feature detection,
and rtcd specialization for this instruction set extension.
