I need to do some code refactoring. I am basically trying to find all
"#include " statements (check for duplicates and add a few of my own etc). I
tried to parse the AST but I realized that the preprocessor has already
converted these statements (to code). Is there any FrontendAction that I can
invoke allowing me to detect and stop at these statements?
