The parallel_deblocking experiment is proposed jointly by Intel
and Microsoft. The following changes are implemented in this
experiment:
- deblocking filter order is changed to filter all vertical edges
of the whole frame followed by filtering all horizontal edges
of the whole frame
- filter length decision is made based on the transform block size
on both sides of the edge. block with smaller transform size
determines the final filter length.
- transform blocks on both sides of the edge are checked, only when
both blocks are skipped and they belong to the same prediction
block, filtering of that edge can be skipped.
- 15-tap filter and extended flat area detection are removed.
- special rule for handling 4x4 transform block on the super block
boundary in VP9 is removed.

The convolve filters generated by loop_wiener_filter_tile
are not compatible with some existing convolve implementations
(they can have coefficients >128, sums of (certain subsets of)
coefficients >128, etc.)
So we implement a new variant, which takes a filter with 128
subtracted from its central element and which adds an extra copy
of the source just before clipping to a pixel (reinstating the
128 we subtracted). This should be easy to adapt from the existing
convolve functions, and this patch includes SSE2 highbd and
SSSE3 lowbd implementations.

- For all blocks with width >= 16.
- Add test_count to make the unit tests harder to pass.
- Speed testing on 1080p, 100 frames, 5 Mbps, CPU, i7-6700
User level time reduction:
baseline: 3.68%
baseline + ext-partition: 36.12%

Let aom_convolve8_### SIMD implementation support any block width.
Turn on SIMD optimization when interpolation filter types on two
directions are different.
This will reduce 30% of encoding time when dual_filter and ext_interp
both on.

While we are at it:
- Rename some variables to more meaningful names
- Reuse some common consts from a header instead of redefining them.
