NEON: implement alpha-filters (horizontal/vertical/gradient)
...
gradient-filter code is not much faster, but maybe improvable in the future.

Add MSA optimized alpha filter functions
...
We add the following MSA optimized alpha filter functions:
- HorizontalFilter
- VerticalFilter
- GradientFilter

update the Unfilter API in dsp to process one row independently
...
This will allow to work in-place on cropped area later.
Also sped up the inverse gradient filtering in SSE2 (~4%)

add SSE2 variants for alpha filtering functions
...
The 'inverse' variants are harder to parallelize, since
the result of filtering is used for prediction.
The 'direct' way is relatively easier.
The heavy bottleneck left for optimization is still GradientUnfilter()
