In practice, this can never happen because:
- 'streak' is at most as long as a histogram
- 'count' counts the number of streaks
'streak' and 'count' are therefore at most as big as the histogram
length which is at most the max of VP8LHistogramNumCodes,
which is 256+24+(1<<10).

The row parameter became a constant in:
2102ccd update the Unfilter API in dsp to process one row independently
num_rows is always equal to height.

The inverse parameter became a constant in:
2102ccd update the Unfilter API in dsp to process one row independently
The row parameter to these functions is in a similar state; it will be
removed in a follow up.

Replace vmovl_u8 -> s16 + signed vaddq with unsigned vaddw.
No change in assembly with clang-16 (armv7 & aarch64) and gcc-13
(aarch64). armv7 gcc-13 had kept the vmovl instructions, those are now
gone.

This brings minor size improvements because repetitive values in
the transform images are easily explainable through LZ77. Still,
it makes an upcoming pull request a bit more stable.

Use QuantizeBlock_NEON for VP8EncQuantizeBlockWHT on Arm
Add AArch64 Neon implementation of Intra16Preds
Add AArch64 Neon implementation of Intra4Preds
Add a Neon implementation of Intra16Preds for use on 64-bit Arm
platforms. (This implementation cannot be used on 32-bit Arm
platforms as it makes use of a number of AArch64-only Neon
instructions.)

Add Neon implementation of Intra4Preds for use on 64-bit Arm

platforms as it uses a number of AArch64-only Neon instructions.)

The lossless encoding speed-ups are:
- up to 1% with default parameters
- up to 4% in cruncher mode: -q 100 -m 6

This reverts commit ee26766a89.
This change also reverts the parent.
Revert "Increase the transform bits if possible."
This reverts commit 7ec51c5916.
These changes result in non-lossless encodes.

This is 971a03d820 with a fix to
not forget to analyze the end of the line.
A const has also been added to match VP8LColorSpaceTransform's
signature.

This reverts commit 971a03d820.
Reason for revert:
This creates non-lossless encodes.

Replace the 2d histograms with uint32_t 1d versions (to avoid
pointer casting and to use the optimized VP8LAddVectorEq).

fixes warnings of the form:
/src/dsp/upsampling_sse41.c:170:1: runtime error: implicit conversion
from type 'int' of value -16 (32-bit, signed) to type 'uintptr_t' (aka
'unsigned long') changed the value to 18446744073709551600 (64-bit,
unsigned)
this is the same change as was done previously in upsampling_sse2.c:
