fa8f53273c refactor: Remove no longer needed clang-15 workaround for std::span (MarcoFalke)
9999dbc1bd fuzz: Clarify Apple-Clang-16 workaround (MarcoFalke)
fa7462c67a build: Bump clang minimum supported version to 16 (MarcoFalke)
Pull request description:
Most supported operating systems ship with clang-16 (or later), so bump the minimum to that and allow new code to drop workarounds for previous clang bugs.
For reference:
* https://packages.debian.org/bookworm/clang-16
* https://packages.ubuntu.com/noble/clang (clang-18)
* CentOS-like 8/9 Stream: All Clang versions from 16 to 17
* FreeBSD 12/13: All Clang versions from 16 to 18
* OpenSuse Tumbleweed ships with https://software.opensuse.org/package/clang (`clang18`); No idea about OpenSuse Leap
On operating systems where the clang version is not shipped by default, the user would have to use GCC, or install clang in a different way. For example:
* https://packages.debian.org/bookworm/g++ (g++-12)
* https://packages.ubuntu.com/jammy/g++ (g++-11)
* https://apt.llvm.org/, or nix, or guix, or compile clang from source, ...
**Ubuntu 22.04 LTS does not ship with clang-16**, so one of the above workarounds is needed there.
macOS 13 is unaffected, and the previous minimum requirement of Xcode15.0 remains, see also b1ba1b178f/.github/workflows/ci.yml (L93). For macOS 11 (Big Sur) and 12 (Monterey) you need to install a more recent version of llvm, this remains unchanged as well, see b1ba1b178f/doc/build-osx.md (L54).
