this was only used in debug builds, the build should be fast enough in
either case.

/Gm is deprecated. It may not trigger a build for certain kinds of
header file changes. You may safely remove this option from your
projects. To improve build times, we recommend you use precompiled
headers and incremental and parallel build options instead.

The output was always 99dB because the lossless pipeline is not
modifying the 'picture'. Changing that is not that simple because
near_lossless impacts both VP8ApplyNearLossless() and
ApplyPredictFilter(); the latter cannot be applied as is to the input
and thus the final modified 'picture' cannot be easily retrieved
without decoding the encoded bitstream. Hence ReadWebP() is called in
cwebp.c on the encoded bitstream kept in memory to get the correct
distortion.
However -get_psnr returns a different distortion than get_disto for
lossy encoding configurations because cwebp loads the source as YUV
while get_disto directly reads it as RGB without conversion loss.

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

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.

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));

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