Clang: Move printing functions in clang support to unit tests

The printing functions are only used by the unit tests and they use an
external API. So we can easily move them to the printing functions in
the unit test project. We have to move the TokenInfo print functions too
because the depend on other print functions. The rest of the print
functions will be moved in other patches.
