Add two String.prototype methods for working with well-formed UTF-16 strings. A JavaScript string value is well-formed UTF-16 if it has no unpaired surrogate code points. By default, JavaScript strings may be ill-formed. - String.prototype.isWellFormed returns whether the receiver string is well-formed UTF-16. - String.prototype.toWellFormed returns a string that is identical to the receiver string, except all unpaired surrogate code points are replaced with U+FFFD (REPLACEMENT CHARACTER).

}Extend the ArrayBuffer constructors to take an additional maximum length that allows in-place growth and shrinking of buffers. Similarly, SharedArrayBuffer is extended to take an additional maximum length that allows in-place growth.
