Move most of the code of inverse_transform_block to
av1_inverse_transform_block such that encoder can use the
function as well.

Use av1_inverse_transform_block in av1_encoder_block_intra.
This will make the code cleaner.

This will simplify the code flow in av1_subtract_txb()

A simpler interface for intra block prediction

This function help us merge subtract block code in
av1_subtract_plane and av1_encode_block_intra.

EXT_TILE: allocate variables on the heap due to the potentially
large number of tiles.

ANS: initialise tile contexts.

EXT_INTER, MOTION_VAR, WARPED_MOTION: fix compilation.

On x86 there is no direct v128_shr_n_s8 equivalent, so
v128_cmplt_s8(a, v128_zero()) is much better than v128_shr_n_s8(a, 7).
Should have no impact on NEON.

Also replace v256_from_v128(v128_from_v64(a, b), v128_from_v64(c, d))
with v256_from_v64(a, b, c, d).

Previous code was using options selected for N=8 rather than the chosen
number of options.

Add boundary testing for both dering and CLPF.  Also add a CDEF prefix
to make it easy to select all CDEF tests.

This makes it clear when profiling that the correct SIMD optimised
function is run.

Rather than having the adjustment in the leaf functions, do the
adjustment in the top-level function.  Optimising compilers would
figure this out themselves as far as the functions are inlined, but
probably no further and this patch gives a slightly reduced object
code size.

As part of 9cf0c9cd the buffering was made
to better handle 4:2:2, but that causes regressions in the tests, so we're
backing out part of it for now.

Only 1 sample needs to be collected. Max of 8 neighbors are
used.
In LS estimation, the projection samples (sx, sy)->(dx, dy) are
intentionally smoothed by assuming 3 shifted versions
(sx, sy+n)->(dx, dy+n), (sx+n, sy)->(dx+n, dy), (sx+n,
sy+n)->(dx+n, dy+n) also contribute to the estimation.
For example, instead of using A[0] = sx^2, we use the sum of
squares of source x of four points, A[0] += 4sx^2+4*n*sx+n^2.
But computational cost wise, it does not add much overhead. Coding
gain is mostly same as the old version. If no smoothing is added,
will lose 0.3% on lowres.

Also rebalance the iterations depending on the bitdepth, since this
made the high bitdepth tests very slow.
