Merge #500: Use clang instead of clang-9

a59028c Use clang instead of clang-9 (Tobin C. Harding)

Pull request description:

  The current version of clang is 14, there is no obvious reason why we use clang-9 (as far as I can tell on my local machine).

  Use `clang` instead of `clang-9` so that the latest version is used by default. This effects the version installed by CI as well as the version used to run commands in `test.sh`.
