- Add getParent() accessors.
- Move SubReg out of the AuxInfo union, to make way for future changes.
- Remove the getImmedValue/setImmedValue methods.
- in some MachineOperand::Create* methods, stop initializing fields that are dead.
MachineInstr:
- Delete one copy of the MachineInstr printing code, now there is only one dump
format and one copy of the code.
- Make MachineOperand use the parent field to get info about preg register names if
no target info is otherwise available.
- Move def/use/kill/dead flag printing to the machineoperand printer, so they are
always printed for an operand.
