    * Code: Generic 32-bit binary operation.  Provides an "instr" line to
    *       specify an instruction that performs "%edx = %edx op %cl"
    *
    * For: shl-int, shr-int, ushr-int
    *
    * Description: Perform a binary operation on two source registers
    *              and store the result in a destination register.
    *
    * Format: AA|op CC|BB (23x)
    *
    * Syntax: op vAA, vBB, vCC
