Functions
	STATISTIC (NumLEAs, "Number of LEA instructions created")
static bool	isLEA (unsigned Opcode)
static bool	getPreviousInstr (MachineBasicBlock::iterator &I, MachineBasicBlock &MBB)
	getPreviousInstr - Given a reference to an instruction in a basic block, return a reference to the previous instruction in the block, wrapping around to the last instruction of the block if the block branches to itself.
static bool	isInefficientLEAReg (Register Reg)
static bool	hasInefficientLEABaseReg (const MachineOperand &Base, const MachineOperand &Index)
	Returns true if this LEA uses base and index registers, and the base register is known to be inefficient for the subtarget.
static bool	hasLEAOffset (const MachineOperand &Offset)
static unsigned	getADDrrFromLEA (unsigned LEAOpcode)
static unsigned	getSUBrrFromLEA (unsigned LEAOpcode)
static unsigned	getADDriFromLEA (unsigned LEAOpcode, const MachineOperand &Offset)
static unsigned	getINCDECFromLEA (unsigned LEAOpcode, bool IsINC)
