Craig Topper d93296dbb4 [InstCombine] Improve support for ashr in foldICmpAndShift ... We can support ashr similar to lshr, if we know that none of the shifted in bits are used. In that case SimplifyDemandedBits would normally convert it to lshr. But that conversion doesn't happen if the shift has additional users.
