  24     ECMA Section:       15.4.2.1 new Array( item0, item1, ... )
  25     Description:        This description only applies of the constructor is
  26                         given two or more arguments.
  27
  28                         The [[Prototype]] property of the newly constructed
  29                         object is set to the original Array prototype object,
  30                         the one that is the initial value of Array.prototype
  31                         (15.4.3.1).
  32
  33                         The [[Class]] property of the newly constructed object
  34                         is set to "Array".
  35
  36                         The length property of the newly constructed object is
  37                         set to the number of arguments.
  38
  39                         The 0 property of the newly constructed object is set
  40                         to item0... in general, for as many arguments as there
  41                         are, the k property of the newly constructed object is
  42                         set to argument k, where the first argument is
  43                         considered to be argument number 0.
  44
  45                         This test stresses the number of arguments presented to
  46                         the Array constructor.  Should support up to Math.pow
  47                         (2,32) arguments, since that is the maximum length of an
  48                         ECMAScript array.
  49
  50                         ***Change TEST_LENGTH to Math.pow(2,32) when larger array
  51                         lengths are supported.
