+ File Name: 11.4.4.js
+ 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).
