    File Name:          9.4-1.js
    ECMA Section:       9.4 ToInteger
    Description:        1.  Call ToNumber on the input argument
                        2.  If Result(1) is NaN, return +0
                        3.  If Result(1) is +0, -0, Infinity, or -Infinity,
                            return Result(1).
                        4.  Compute sign(Result(1)) * floor(abs(Result(1))).
                        5.  Return Result(4).

                        To test ToInteger, this test uses new Date(value),
                        15.9.3.7.  The Date constructor sets the [[Value]]
                        property of the new object to TimeClip(value), which
                        uses the rules:

                        TimeClip(time)
                        1. If time is not finite, return NaN
                        2. If abs(Result(1)) > 8.64e15, return NaN
                        3. Return an implementation dependent choice of either
                        ToInteger(Result(2)) or ToInteger(Result(2)) + (+0)
                        (Adding a positive 0 converts -0 to +0).

                        This tests ToInteger for values -8.64e15 > value > 8.64e15,
                        not including -0 and +0.

                        For additional special cases (0, +0, Infinity, -Infinity,
                        and NaN, see 9.4-2.js).  For value is String, see 9.4-3.js.
