The only difference between the two was that the vp9 function allowed
for every step in the bilinear filter (16 steps) while vp8 only allowed
for half of those. Since all the call sites in vp9 (<< 1) the input, it
only ever used the same steps as vp8.
This will allow moving the subpel variance to vpx_dsp with the rest of
the variance functions.

Adds code to detect dead zone bars at the top and bottom
of reformatted letterbox video (note that the code only
looks at the top of the image and assumes any dead zone
is symmetrical). Use of this to adapt rate control etc.
will follow in a subsequent patch.
Also counts other blocks (excluding the dead zone) that
have no intra signal. The presence of a significant
number of such blocks can be used as a identify that the frame
may be artificial (e.g. animation, screen capture, graphics).
This patch contains plumbing only and does not use
the signal.

Some places are using the unoptimized variance function. This was never
intended and does not fit into the optimization framework.

Updated sources according to improved version of common MSA macros.
Enabled respective convolve MSA hooks and tests.
Overall, this is just upgrading the code with styling changes.

Clang adds alignment hints when casting up the loads/stores. Although
this should be safe for most paths, it's causing some crashes. Either
the source of the misalignment needs to be determined and adjusted or
the intrinsics need to be rewritten to avoid using the cast to load the
data.

The larger internal variables are required for the intermediates
but RoundHighBitDepth brings them down to uint32_t/unsigned int.
Fixes type warnings in visual studio.

Numerator was being range checked against the
denominator - preventing any frame rate slower
than 1 fps.
I've tested this on a Mac using using ffmpeg and
results are comparable to mp4 and ogg files generated
at the same time.
Not yet tested on Windows.

only the immediate above right pixel is needed; this removes a
conditional from the inner loop
the final average calculated currently relies on above[] being extended,
it could be reduced to use above[block_size - 2] + 3 * above_right
