static bool AreEquivalentAddressValues	(	const Value *	A,
		const Value *	B
	)			[static]

AreEquivalentAddressValues - Test if A and B will obviously have the same value. This includes recognizing that t0 and t1 will have the same value in code like this: t0 = getelementptr , 0, 3 store i32 0, i32* t0 t1 = getelementptr , 0, 3 t2 = load i32* t1
