Continue processing sets of 16 values. Plenty of improvement for 4x8
(doubles the speed) but only about 30% for 4x4.

Add support for everything except block sizes of 4.
Performance is better but numbers will improve again when the variance
optimizations land.

Some of the mixed sizes were missing. They can be implemented trivially
using the existing helper function.
When comparing the previous 16x8 and 8x16 implementations, the helper
function is about 10% faster than the 16x8 version. The 8x16 is very
close, but the existing version appears to be faster.

- Use arithmetic AND (&) instead of logical AND (&&) to
generate correct testing input.
- Fix variance reference function to be consistent with
our codebase implementation.

Always round sum error and sum square error toward zero in variance
calculations. This prevents variance from becoming negative.
Avoiding rounding variance at all might be better but would be far
more invasive.

[ FAILED ] NEON/VP8SubpelVarianceTest.ExtremeRef/0, where GetParam() = (3, 3, 0x14e36d, 0)

the tests were recently enabled in:
eb88b17 Make vp9 subpixel match vp8
the functions likely haven't changed since being converted from assembly
Change-Id: I6141717b111b8f735f436c160d74270af53ef722
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.

The larger internal variables are required for the intermediates
but RoundHighBitDepth brings them down to uint32_t/unsigned int.

ROUND_POWER_OF_TWO has some poor side effects when used
with [u]int64_t such as doing the shifting in 32bits.

With the sad functions, and hopefully the variance functions soon,
moving to the vpx_dsp location, place the defines used in the
reference C code in a common location.
