// 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}
// I = immediate displacement (int32_t)
