…tracts, r=nnethercote Fix ICE in tokenstream with contracts from parser recovery Fixes rust-lang#140683 After two times of parsing error, the `recover_stmt_` constructs an error ast, then when we expand macors, the invalid tokenstream triggered ICE because of mismatched delims. Expected `{` and get other tokens is an obvious error message, too much effort on recovery may introduce noise. r? `@nnethercote`
