Next step toward supporting migrating headers. Instead of using ClangTool's ability to override all files at once, use a custom FrontendAction and override only the source (and eventually headers) the action is about to parse. Use of newFrontendActionFactory() is replaced with a new factory maker provided by Transform. llvm-svn: 183855
