[cfe-dev] Run clang plugin as additional step

[Bernardo Rufino]

I found the -add-plugin option, but it doesn't really let me modify the
AST, the relevant part is in this file
<http://clang.llvm.org/doxygen/FrontendAction_8cpp_source.html> line 147.
Due to this explicit restriction I feel that modifying the AST through
plugins is not a solution. Where should I do this?
