If a two-byte string only contains ascii characters, then we can save memory when flattening a cons string containing it. Similarly we can use this in Array.prototype.join implementation. To track this a new bit is added to instance type. This bit is used as a hint in generated code and in runtime functions. To enable testing a new V8 extension is added controlled by --expose-externalize-string flag.
