+1. Thanks, @mkazantsev. I think this is a good small incremental fix. If really needed (i.e., others like InstCombine refuses to improve whatever shortcomings exposed), we can add more peephole optimization ---- but I sincerely hope we don't have to do it. Induction simplification is generally useful.
