Don't spin expanding stmt macros. If we can't make progress when parsing a macro expansion as a statement then we should just bail. This alleviates the symptoms shown in e.g. #37113 but it doesn't fix the problem that parsing invalid enum bodies (and others) leaves the parser in a crappy state. 2016-10-18 04:01:36 +00:00			`macro_rules! failed {`
