static bool isADDADDMUL	(	SDValue	Op,
		SDValue &	Mul0,
		SDValue &	Mul1,
		SDValue &	Addend0,
		SDValue &	Addend1,
		bool	requireIntermediatesHaveOneUse
	)		[static]

isADDADDMUL - Return whether Op is in a form that is equivalent to add(add(mul(x,y),a),b). If requireIntermediatesHaveOneUse is true then each intermediate result in the calculation must also have a single use. If the Op is in the correct form the constituent parts are written to Mul0, Mul1, Addend0 and Addend1.
