The patch introduces new way of narrowing complex (>UINT16 variants) solutions.
The new method introduced under "-lsr-exp-narrow" option (currenlty set to true).
Summary:
The method is based on registers number mathematical expectation and should be
generally closer to optimal solution.
Please see details in comments to
"LSRInstance::NarrowSearchSpaceByDeletingCostlyFormulas()" function
(in lib/Transforms/Scalar/LoopStrengthReduce.cpp).
