Seems like upstream LLVM/Clang packaging still has issues with
llvm/clang 17. Fallback to 16 again, for now.

Development on LLVM 16 has started and version 15 is no longer available
in the repository we install it from. Bump the version we use
accordingly.

We are no longer using Travis. As such, it is confusing to anyone
reading the code to see a function prefixed 'travis_' in GitHub actions
code.
This change renames the travis_fold function to 'foldable', as a first
step towards eliminating such confusing constructs from the repository
where possible.
