cpp11-migrate: New mechanism for overriding file contents

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.
