 // 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:
 //
 // R = register
 // O = register or stack slot
 // D = double register
 // I = immediate (handle, external, int32)
 // MRI = [register + immediate]
 // MRR = [register + register]
