2565fa8ffb README.webp_js: update cmake command
remove EMSCRIPTEN_GENERATE_BITCODE_STATIC_LIBRARIES, this option is only
supported with the deprecated fastcomp backend; the wasm version will
begin to throw an error if it's used. 1.39.12 already fails to build when
using this option.

This is particularly useful for multi-pass search (but not only),
to prevent the search from going over or below a reasonable threshold.
E.g.: 'cwebp -qrange 50 80 ...' will prevent any unreasonable degradation.

af650c0bd2 Fix a Wxor-used-as-pow false positive
Since people seem to write "2 ^ X" hoping that it means "1 << X", clang
recently added a warning for this pattern.

It incorrectly fires on this file. To suppress it, restructure the code
to be less clever. (Alternatively we could use "xor" instead of "^" or
write "0x2" instead of "2" but both seem worse.)

No intended behavior change.

0e48d889eb bugfix: last alpha rows were incorrectly decoded
sometimes, the last rows of the alpha plane contain more than NUM_ARGB_CACHE_ROWS
rows to process. But ExtractAlphaRows() was repeatedly calling ApplyInverseTransforms()
without updating the dec->last_row_ field, which is the starting row used as starting
point.

Fix would consist of either updating correctly dec->last_row_ before calling
ApplyInverseTransforms(). Or pass the starting row explicitly, which is simpler.

9d6988f44d Fix the oscillating prediction problem at low quality
For some exact resonance the over-quantization was exactly
compensating the under-quantization, leading to resonance
and strange patterns.

-> we special-handle the very flat blocks, hopefully for the
greater good (and not just the bad-resonance case).

For 'fast mode' (-m 3 or less), we just pay special attention
to the border of the image, where the oscillation / instability
usually starts. For the inner part of the image, since we're not
doing rd-opt, it's harder to fix anything.

Overall, on 'regular' images, the change is written the noise,
often leading to overall faster encoding (because of the short-cut).
