- Let MachineInstr ctors add implicit def and use operands. Other operands
...
will be inserted before these operands. If the opcode changes (by
setOpcode), the implicit operands are updated as well.
- Added IsKill, IsDead fields to MachineOperand in preparation for changes
that move kill / dead info to MachineInstr's.
