VerticalUnfilter_SSE2 has long been disabled due to a crash in an
Android emulator that hasn't reproduced elsewhere (crbug.com/654974).
this synchronizes the code for now to avoid needing to locally edit the
file on import.

this function produces different results from the C code due to
use of double/float resulting in output differences when compared to
-noasm.

It's explicitly safe (and recommended!) to plug external data into
the pic->y/u/v/argb fields. They are guaranteed to be preserved
by the encoding process if no conversion is needed.

- Add `-msimd128` to flags to actually enable WebAssembly SIMD
when performing SIMD detection. It's currently required in
addition to `-msse*` / `-mfpu=neon` flags which only perform
translation of corresponding intrinsics to Wasm SIMD ones.
See a discussion at emscripten-core/emscripten#12714 for
automating this and making easier in the future.
- Remove compilation branch that prevented definitions of
`WEBP_USE_SSE` and `WEBP_USE_NEON` on Emscripten even when
SIMD support was detected at compile-time.
- Add an implementation of `VP8GetCPUInfo` for Emscripten which
uses static `WEBP_USE_*` flags to determine if a corresponding
SIMD instruction is supported. This is because Wasm doesn't
have proper feature detection (yet) and requires making separate
build for SIMD version anyway.

The offset *can* be negative, but the sanitizer reports strange
address behaviour when row_offset is unsigned size_t.
For safety, use int64_t instead (probably overkill. int32_t is probably ok).

After ParseAnimationFrame() calls StoreFrame(), check if StoreFrame() reads
more than anmf_payload_size bytes from dmux->mem_. Treat that as PARSE_ERROR.

this provides stronger synchronization when pthreads are available as
was done in 'd77bf512 add WEBP_DSP_INIT / WEBP_DSP_INIT_FUNC' for the
other init functions.

Fix another pessimization found by the pingo image compressor.
Refactoring is necessary to make LZ77 computation
common to cache or no-cache analysis.

qmin / qmax are now using the pad[] spot at the end of the struct,
and we don't need to bump the ABI major number.

this was not giving a good alpha value, making the method 5/6 a little
blurrier than method 4 (!).

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.

PredictorSub0_SSE2 doesn't use 'upper' (neither does
VP8LPredictorsSub_C[0]); just pass NULL when dealing with trailing
pixels to avoid undefined behavior when offsetting a NULL pointer

some toolchains may implement vcreate_u64 as an assignment to a vector
causing a type mismatch:
invalid conversion between vector type 'uint64x1_t' (vector of 1
'uint64_t' value) and integer type 'unsigned int' of different size
const uint64x1_t LKJI____ = vcreate_u64(L | (K << 8) | (J << 16) | (I << 24));

The workaround for GCC ARM must not be applied when another toolchain
(like MSVC) is used for the build.

'upper' could be NULL and it would be increased.
But that is for predictor zero that does not use 'upper'.

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.

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.
