rustc: Correctly pretty-print macro delimiters This commit updates the `Mac_` AST structure to keep track of the delimiters that it originally had for its invocation. This allows us to faithfully pretty-print macro invocations not using parentheses (e.g. `vec![...]`). This in turn helps procedural macros due to #43081. Closes #50840 2018-05-22 15:01:21 +00:00
