This filter is meant to replace the bilateral filter,
but is currently added in addition to the bilateral filter
for testing.

Replace hard coded numbers with table fetch. Support scalability in
transform block operating unit.

Change-Id: I4a5e67576e72de4936ac52d1401412ca6217ed6d

Refactor to remove the assumption that transform block operates in
the unit of 4x4. This generalizes the codec to support 2x2 transform
block later.

The final ANS state gets further compacted because aliasing the super
frame marker is not an issue.

For some historical reason, coefficients of interpolation filters
in filter.c is defined in int16_t but use 8 bits only.
On the other hand, SIMD like to use int8_t to represent those
coefficients for economical reason.
The conversion from int16_t to int8_t will introduce
"possible loss of data" warning.

We use cast to work around this problem.

Use the atom transform block as the unit to count transform block
orders. This avoids the assumption that the codec goes in unit of
4x4 block.

Control the loop over transform blocks in the unit of smallest
transform block size. This would provide scalability to support
smaller transform block sizes.

This should have no effect on the bitstream format (see also no related
encoder change). This is like moving code from the top of the loop to
the bottom of the loop.

This change allows us to:
* Make sure we consume the final renormalization byte after the last
symbol in an ANS partition.
* Move back toward a single renormalization operation for some ANS modes
since we know the bounds of the state mutation algorithm that got us out
of the valid state range.

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.
