AssignmentExpression:
LeftHandSideExpression AssignmentOperator AssignmentExpression
1. Let lref be the result of evaluating LeftHandSideExpression.
2. Let lval be ? GetValue(lref).
3. Let rref be the result of evaluating AssignmentExpression.
4. Let rval be ? GetValue(rref).
5. Let op be the @ where AssignmentOperator is @=.
6. Let r be the result of applying op to lval and rval as if evaluating the expression lval op rval.
7. Perform ? PutValue(lref, r).
8. Return r.
