    ECMA Section:       11.4.4 Prefix increment operator
    Description:
    The production UnaryExpression : ++ UnaryExpression is evaluated as
    follows:

    1.  Evaluate UnaryExpression.
    2.  Call GetValue(Result(1)).
    3.  Call ToNumber(Result(2)).
    4.  Add the value 1 to Result(3), using the same rules as for the +
        operator (section 11.6.3).
    5.  Call PutValue(Result(1), Result(4)).
    6.  Return Result(4).
