The parser will now always generate Identifier nodes (for non-namespaced identifiers). This obsoletes the useIdentifierNodes parser option. Node constructors still accepts strings and will implicitly create an Identifier wrapper. Identifier implement __toString(), so that outside of strict-mode many things continue to work without changes.
