Auto merge of #37246 - goffrie:no-loop, r=jseyfried
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 and #37234 but it doesn't fix the problem that parsing invalid enum bodies (and others) leaves the parser in a crappy state. I'm not sold on this strategy (checking `tokens_consumed`), so if anyone has a better idea, I'm all ears!
