When deciding whether the top-right or bottom-left blocks are
available, we currently always act as if we're using 128x128
superblocks. This means that, when using 64x64 superblocks,
we sometimes conclude that blocks are available when they haven't
been decoded yet!

This typically happens at, for example, mi_row=15, mi_col=16
(for bottom left), where we're at a 64x64 boundary but not
a 128x128 boundary.

This patch fixes the issue by checking based on the signalled
superblock size.

Note: Most of this patch is just threading 'cm' through the
intra prediction process, so that we have access to cm->sb_size
in has_top_right() and has_bottom_left()

Earlier, the condition was negating all non-directional modes to check
if a mode is directional. This was error-prone, e.g. when a new
non-directional mode is added.

By checking for directional modes directly, we avoid such errors.

Encode a block line by line, horizontally or vertically. In the vertical
mode, each row is predicted by the reconsturcted row above;
in the horizontal mode, each column is predicted by the reconstructed
column to the left.

The DPCM modes are enabled automatically for blocks with horizontal or
vertical prediction mode, and 1D transform types (ext-tx).

When macro REDUCE_INTERINTRA_MODES is 1, only 4 ii modes are enabled
so as to reduce the complexity overhead.

1) block_raster_idx is actually raster order only when tx_size
is TX_4x8.
It's very specific, so we should put it near to the place it's
actually used.

2) Sync the meaning of block_idx on encoder/decoder sides

A simpler interface for intra block prediction

Now that https://aomedia-review.googlesource.com/#/c/6729/
has been merged, build_intra_predictors_for_interintra() is
now redundant, so replace it by a direct call to
av1_predict_intra_block() and remove the old function.

Reset rect_interintra back to 1.

To do this, we need to make the intra predictor take a
BLOCK_SIZE instead of a TX_SIZE. This is because we need to
be able to predict 32x64 and 64x32 blocks, but there is no
TX_32X64 or TX_64X32.

No effect on output or performance.
