Requires use of new cmake toolchain file:
$ cmake path/to/aom -DCMAKE_TOOLCHAIN_FILE=path/to/aom/build/cmake/toolchains/mips32-linux-gcc.cmake
DSPR2 and MSA are supported via addition of -DENABLE_DSPR2=1 and
-DENABLE_MSA=1 respectively. Note that the latter requires the addition
of -DMIPS_CPU=p5600.

A similar cleanup happened before, but the empty statements have since
reappeared. I added a check in 'specialize' subroutine to die whenever
such an empty specialize call is found, so that config+make would fail.

Enables Wiener based loop restoration only for the UV
frames. The selfguided and domaintranform filters do not
work very well for UV components, hence they are disabled.
For each UV frame a single set of wiener parameters are
sent. They are applied tile-wise, but all tiles use the
same parameters.
BDRATE (Global PSNR) results:
-----------------------------
lowres: -1.266% (up from -0.666%, good improvement)
midres: -1.815% (up from -1.792%, tiny improvement)
Tiling on UV components will be explored subsequently.

The global motion detection only works on 8-bit buffers,
so any frames using 16-bit buffers are now down-converted
to 8 bits when necessary.

This avoids explicitly casting them to 'int' later.
These methods were already called with signed int arguments for pitch,
so this also avoids int -> unsigned int -> int conversion.

For example, loops of the form:
"for (i = 0; i < 1 + max_value; ++i) ..." or
"for (i = 0; i <= max_value; ++i) ..." are possibly infinite loops,
theoretically speaking (even if practically, they aren't).
So, compiler cannot optimize those loops.
When possible, I rewrote such loops to be finite even theoretically.
