LibJS: Distinguish between statement and declaration This separates matching/parsing of statements and declarations and fixes a few edge cases where the parser would incorrectly accept a declaration where only a statement is allowed - for example: if (foo) const a = 1; for (var bar;;) function b() {} while (baz) class c {} 2020-10-22 23:30:07 +01:00			`test("Declaration in single-statement context is a syntax error", () => {`
