    * Code: Generic 32-bit comparison operation. Provides a "revcmp"
    *       variable to specify the reverse comparison to perform.
    *
    * For: if-eq, if-ge, if-gt, if-le, if-lt, if-ne
    *
    * Description: Branch to the given destination if the comparison
    *              test between the given registers values is true.
    *
    * Format: B|A|op CCCC (22t)
    *
    * Syntax: op vA, vB, +CCCC
