bool BuildVectorSDNode::isConstantSplat	(	APInt &	SplatValue,
		APInt &	SplatUndef,
		unsigned &	SplatBitSize,
		bool &	HasAnyUndefs,
		unsigned	MinSplatBits = `0`,
		bool	isBigEndian = `false`
	)

isConstantSplat - Check if this is a constant splat, and if so, find the smallest element size that splats the vector. If MinSplatBits is nonzero, the element size must be at least that large. Note that the splat element may be the entire vector (i.e., a one element vector). Returns the splat element value in SplatValue. Any undefined bits in that value are zero, and the corresponding bits in the SplatUndef mask are set. The SplatBitSize value is set to the splat element size in bits. HasAnyUndefs is set to true if any bits in the vector are undefined. isBigEndian describes the endianness of the target.
