    ECMA Section:       11.13.2 Compound Assignment: %=
    Description:

    *= /= %= += -= <<= >>= >>>= &= ^= |=

    11.13.2 Compound assignment ( op= )

    The production AssignmentExpression :
    LeftHandSideExpression @ = AssignmentExpression, where @ represents one of
    the operators indicated above, is evaluated as follows:

    1.  Evaluate LeftHandSideExpression.
    2.  Call GetValue(Result(1)).
    3.  Evaluate AssignmentExpression.
    4.  Call GetValue(Result(3)).
    5.  Apply operator @ to Result(2) and Result(4).
    6.  Call PutValue(Result(1), Result(5)).
    7.  Return Result(5).
