    ECMA Section:       15.4.2.1 new Array( item0, item1, ... )
    Description:        This description only applies of the constructor is
                        given two or more arguments.

                        The [[Prototype]] property of the newly constructed
                        object is set to the original Array prototype object,
                        the one that is the initial value of Array.prototype
                        (15.4.3.1).

                        The [[Class]] property of the newly constructed object
                        is set to "Array".

                        The length property of the newly constructed object is
                        set to the number of arguments.

                        The 0 property of the newly constructed object is set
                        to item0... in general, for as many arguments as there
                        are, the k property of the newly constructed object is
                        set to argument k, where the first argument is
                        considered to be argument number 0.

                        This test stresses the number of arguments presented to
                        the Array constructor.  Should support up to Math.pow
                        (2,32) arguments, since that is the maximum length of an
                        ECMAScript array.

                        ***Change TEST_LENGTH to Math.pow(2,32) when larger array
                        lengths are supported.
