Public Member Functions
	PartialReductionChain (Instruction *Reduction, Instruction *ExtendA, Instruction *ExtendB, Instruction *ExtendUser)

Public Attributes
Instruction *	Reduction
	The top-level binary operation that forms the reduction to a scalar after the loop body.
Instruction *	ExtendA
	The extension of each of the inner binary operation's operands.
Instruction *	ExtendB
Instruction *	ExtendUser
	The user of the extends that is then reduced.

Detailed Description

A chain of instructions that form a partial reduction.

Designed to match either: reduction_bin_op (extend (A), accumulator), or reduction_bin_op (bin_op (extend (A), (extend (B))), accumulator).
