Some tooling components are not dependent much on what semantics an
AST node represents. Some ideas:

 * clang-query/ASTMatcher, especially those that check for the node type only.

 * clang-tidy: Just have a different set of checkers for
C/C++/ObjC/Fortran; (As alternative to duplicating or templating code
on Fortran/Clang AST types)

 * clang-diff

 * serialization/deserialization of ASTs

 * graphviz visualization
