This adds the -Rmacro-expansions flag. It provides similar functionality to -dump-macro-expansions, but instead of dumping the macro expansion to stderr, it emits it line by line as remarks. This is useful for testing with -verify, where both macro expansion content and warnings need to be tested at the same time.
