Allow identifier code points from supplementary multilingual planes. ES5.1 section 6 ("Source Text"): "Throughout the rest of this document, the phrase “code unit” and the word “character” will be used to refer to a 16-bit unsigned value used to represent a single 16-bit unit of text." This changed in ES6 draft section 10.1 ("Source Text"): "The ECMAScript code is expressed using Unicode, version 5.1 or later. ECMAScript source text is a sequence of code points. All Unicode code point values from U+0000 to U+10FFFF, including surrogate code points, may occur in source text where permitted by the ECMAScript grammars." This patch is to reflect this spec change.
