 * Instruction Factory - Data-driven instruction set builder

 * 2. Not importing CPU types in instruction definitions
 * 3. Allowing CPU to optionally use instruction builders
 *
 * Instructions are defined as data (opcode -> function mapping) rather than
 * hard-coded in the CPU or instruction table files.
