template<unsigned N>
static bool	isGreaterThanNBitTFRI (const MachineInstr &I)
static bool	areCombinableOperations (const TargetRegisterInfo *TRI, MachineInstr &HighRegInst, MachineInstr &LowRegInst, bool AllowC64)
	areCombinableOperations - Returns true if the two instruction can be merge into a combine (ignoring register constraints).
static bool	isEvenReg (unsigned Reg)
static void	removeKillInfo (MachineInstr &MI, unsigned RegNotKilled)
static bool	isUnsafeToMoveAcross (MachineInstr &MI, unsigned UseReg, unsigned DestReg, const TargetRegisterInfo *TRI)
	Returns true if it is unsafe to move a copy instruction from UseReg to DestReg over the instruction MI.
static Register	UseReg (const MachineOperand &MO)
