 // Addressing modes represent the "shape" of inputs to an instruction.
 // Many instructions support multiple addressing modes. Addressing modes
 // are encoded into the InstructionCode of the instruction and tell the
 // code generator after register allocation which assembler method to call.
 //
 // We use the following local notation for addressing modes:
 //
 // M = memory operand
 // R = base register
 // N = index register * N for N in {1, 2, 4, 8}
