     19     * Code: Generic 64-bit binary operation.  Provides an "instr" variable to
     20     *       specify an instruction that performs "%xmm0 = %xmm0 op %xmm1"
     21     *
     22     * For: add-double, add-long, and-long, mul-double, or-long,
     23     *      sub-double, sub-long, xor-long
     24     *
     25     * Description: Perform a binary operation on two source registers
     26     *              and store the result in a destination register.
     27     *
     28     * Format: AA|op CC|BB (23x)
     29     *
     30     * Syntax: op vAA, vBB, vCC
