As long as clang-tools-extra is an optional component, it makes no
sense to me to have tests for PPCallbacks out there.

The lexer's interaction with PPCallbacks is critical functionality for
many tools, and it would be nice if that was tested irrespective of
whether there's a pp-trace tool or not.

For what it's worth,
