Produce an estimate of the unrolled cost of the specified loop.
Synopsis
Declared in <llvm/Transforms/Utils/UnrollLoop.h>
class UnrollCostEstimator;Description
This is used to a) produce a cost estimate for partial unrolling and b) to cheaply estimate cost for full unrolling when we don't want to symbolically evaluate all iterations.
