[PATCH] D30708: [ARM] SMULW [T|B] DAG Combine

Yes ok, I had hoped that more code could be refactored out of the other backends since most of the uses were for low bit masks, but it makes more sense to a flexible API.  This makes the interface very similar to TLO::SimplifyDemandedBits, do you know why that function is set to assume a single use?
