Linus Groh b4e51249e9 LibJS: Always insert semicolon after do-while statement if missing
https://tc39.es/ecma262/#sec-additions-and-changes-that-introduce-incompatibilities-with-prior-editions

11.9.1: In ECMAScript 2015, Automatic Semicolon Insertion adds a
semicolon at the end of a do-while statement if the semicolon is
missing. This change aligns the specification with the actual behaviour
of most existing implementations.
