// 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)
// MR = [register]
// MI = [immediate]
// MRN = [register + register * N in {1, 2, 4, 8}]
// MRI = [register + immediate]
// MRNI = [register + register * N in {1, 2, 4, 8} + immediate]
