Omitting the C-only functions doesn't speed up benchmarking
anyway (as those has to be benchmarked before we know if we have
any corresponding assembly functions), and being able to benchmark
those functions without corresponding assembly can be valuable in
a number of cases.

xHE-AAC is a profile where some frames depend on other key frames, named IPF.
By setting the codec as Intra Only, all frames output by decoders and all
packets output by encoders/demuxers will be unconditionally flaged as
keyframes, which is incorrect.

The logic did not follow the documented behaviour and that caused skipping of
some audio in the loop and in the leftover buffer.
Example command line which should produce a smooth sine wave for the whole

The JPEG XL parser has an entropy decoder inside, which supports LZ77
length-distance pairs. If the first symbol from the entropy stream is an
LZ77 pair, the bitstream is invalid, so we should abort immediately rather
than attempt to read it anyway (which would read from the uninitialized
starting window).

This commit introduced a regression to VVC_HDR_UHDTV1_OpenGOP_3840x2160_50fps_HLG10_mosaic.ts.
Root Cause:
The AV_CEIL_RSHIFT(a, b) macro uses bit tricks that work only when -a is a negative value.
However, due to integer promotion rules, this behavior does not extend to the unsigned int type.
See "6.3.1.1 Boolean, characters, and integers" in the "ISO/IEC 9899" for details.
