[PATCH] D19871: Add an AST matcher for CastExpr kind

Is this required for some purpose?

I'm not keen on adding new AST matchers that we cannot expose via the dynamic API, so I would prefer to solve that problem if we want to add this matcher.

Also, be sure to regenerate the documentation from dump_ast_matchers.py
