Acid3 expects JSC to ignore Unicode CF chars when parsing

We throw an exception here, instead of ignoring U+2062.  I expect there are other CF codepoints which we are supposed to ignore as well.

    function () {
      // test 84: ES3 section 7.1 (Cf characters are ignored)
      var times = "\u2062"; // U+2062 INVISIBLE TIMES
      var v1 = eval("2" + times + "3");
      assert(v1 == 23, "U+2062 was not ignored when parsing script");
      return 6;
    },

This is a duplicate of bug 4931 and a WONTFIX, unless there is some new data to consider.

I'll mark this as duplicate. I Hixie's probably going to omit this from Acid3.
