MachineType is now a class with two enum fields: - MachineRepresentation - MachineSemantic Both enums are usable on their own, and this change switches some places from using MachineType to use just MachineRepresentation. Most notably: - register allocator now uses just the representation. - Phi and Select nodes only refer to representations.
