Properly handle emojis as literal prefix in macros Do not accept the following ```rust macro_rules! lexes {($($_:tt)*) => {}} lexes!(🐛"foo"); ``` Before, invalid emoji identifiers were gated during parsing instead of lexing in all cases, but this didn't account for macro expansion of literal prefixes. Fix #123696. 2024-04-10 21:12:45 +00:00			`macro_rules! lexes {($($_:tt)*) => {}}`

			`lexes!(🐛#); //~ ERROR identifiers cannot contain emoji`
			`lexes!(🐛"foo");`
			`lexes!(🐛'q');`
			`lexes!(🐛'q);`

			`fn main() {}`
