/**
File Name: 11.3.2.js
ECMA Section: 11.3.2 Postfix decrement operator
Description:
11.3.2 Postfix decrement operator
The production MemberExpression : MemberExpression -- is evaluated as follows:
1. Evaluate MemberExpression.
2. Call GetValue(Result(1)).
3. Call ToNumber(Result(2)).
4. Subtract the value 1 from Result(3), using the same rules as for the -
operator (section 0).
5. Call PutValue(Result(1), Result(4)).
6. Return Result(3).
