The combination of -Wunused-macro and -frewrite-includes still doesn't really work with this patch applied: if the only use of a macro is within a preprocessor directive that -frewrite-includes expands, we'll still warn about it. Unfortunately I don't have any great ideas as to how to solve this; the least bad idea I have is to add a '#pragma clang macro_used BLAH', and emit that for each macro that's used in the -frewrite-includes run.
