    Description:
    Semantics

    The production A : A @ B, where @ is one of the bitwise operators in the
    productions &, ^, | , is evaluated as follows:

    1.  Evaluate A.
    2.  Call GetValue(Result(1)).
    3.  Evaluate B.
    4.  Call GetValue(Result(3)).
    5.  Call ToInt32(Result(2)).
    6.  Call ToInt32(Result(4)).
    7.  Apply the bitwise operator @ to Result(5) and Result(6). The result is
        a signed 32 bit integer.
    8.  Return Result(7).
