The masked variance functions can read slightly off the
(nominal) end of their input array. This is not a problem,
since the extra data is never used, and when the functions
are used in the encoder proper, they will just read data
from the frame border.

However, the arrays in the test case had not been properly
padded, causing ASan to complain about reading off the end
of an array.

Also remove an accidental comment in the code.

* Simplify the C version of the warp filter to make the intent
  of the code clearer
* Replace saturate_uint() in the C warp filter with an assertion
  that the intermediate values are in-range. This is because they
  should (provably) *never* go out-of-range.
* Add a comment describing the intended hardware architecture
* Miscellaneous comment updates

Implements the high precision Wiener filter with an offset
to reduce the error due to saturation without increasing
the number of bits needed for intermediate precision.

Also turns the high precision filter on.

We would expect that these new functions would be slower than
the old masked SAD/SSE functions, as they do additional work
(blending two inputs and comparing to a third, rather than
just comparing two inputs).

This is true for the SAD functions, which are about 50% slower
(depending on block size and bit depth). However, the sub-pixel
SSE functions are comparable to the old speed for the accelerated
special cases (xoffset or yoffset = 0 or 4), and are
between 40-90% faster for the generic case.

Changes av1_scale_if_required to check if a resize is needed using the
width and height from cm directly rather than cm's mi_cols and mi_rows
times MI_SIZE.

This is simpler, and won't have issues with sizes that aren't divisible
by MI_SIZE.

This fixes an issue with context clearing introduced by commit
5e81643d.

In av1_zero_above_context width_y went from being assigned "2 *
aligned_width" to "width << 1". All this patch does is replace width
with the aligned_width.

This resolves an issue with random resizing being broken on the master
branch.

In both versions of av1_optimize_b, the code to calculate the
dequantized coefficient from a modified quantized coefficient
was not compatible with tx64x64.

Specifically, the new dequantized coefficient was calculated as an
offset applied to the original coefficient. This had a fixup block
for 32x32 transforms, but not for 64x64 transforms.

For simplicity, instead of extending the fixup block, we now
recalculate the dequantized coefficient directly.
