This is to avoid compiler warning of "mixed declarations and code".

This commit renames a few test from SSE4_1_C_COMPARE/* to SSE4_1/* to
be consistent with the rest of the codebase and friendly to the setup
of jenkins.

Separate the use cases of number of 8x8 blocks from those of
mode_info array. This allows the mode_info array processing to be
scaled to 4x4 resolution.

The module blocks are now scaled to operate in the unit of 2x2
blocks. This commit makes the sub8x8 intra mode RD search compatible
with such assumption.

Relative to previous ext-inter:
lowres: -0.177%
     or -0.029% (with USE_RECT_INTERINTRA = 0)

* When predicting interintra modes, the previous code did not provide
  the intra predictor with the correct context during rdopt. Add an
  explicit 'ctx' parameter to the relevant functions, to provide this
  context.
  This fixes a nondeterminism bug, which was causing test failures in
  *EncoderThreadTest*

* For rectangular blocks, build_intra_predictors_for_interintra needs
  to overwrite part of the context buffer in order to set up the
  correct context for intra prediction. We now restore the original
  contents afterwards.

* Add a flag to enable/disable rectangular interintra prediction;
  disabling improves encoding speed but reduces BDRATE improvement.

Map the block offset to pixel positions in the unit of minimum
transform block size. This change retains the same coding
statistics. The encoding speed is slightly faster (<1%).

Temporarily increase the buffer size from 2 to 4 in the sub8x8

after cb4x4 is fully enabled.

This filter is meant to replace the bilateral filter,

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

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.
