    // * B: 0xCC
    // * C: 0xAA
    //
    // To compute the correct control byte, you simply perform the corresponding operation on these keys. So, if you

    //
    // This table allows us to compute the inverse information, that is given a control, what are the operations it
    // performs. This allows us to determine things like what operands are actually used (so we can correctly compute
    // isRMW) and what operations are performed and in what order (such that we can do constant folding in the future).
    //
    // The total set of operations supported are:
    // * true:   AllBitsSet
    // * false:  Zero
    // * not:    ~value
    // * and:    left & right
    // * nand:   ~(left & right)

    // * nor:    ~(left | right)
    // * xor:    left ^ right
