19    * Code: 32-bit "lit8" divide operation. Provides an "instr" line
20    *       to specify an instruction that performs  "%ecx = %ecx op %edx"
21    *
22    *
23    * For: add-int/lit8, and-int/lit8, mul-int/lit8, or-int/lit8

25    *
26    * Description: Perform a binary operation on a register and a
27    *              signed extended 8-bit literal value
28    *
29    * Format: AA|op CC|BB (22b)
