Sanjay Patel 3d039197d7 [InstCombine] optimize unsigned icmp of increment ... Allows LLVM to optimize sequences like the following: %add = add nuw i32 %x, 1 %cmp = icmp ugt i32 %add, %y Into: %cmp = icmp uge i32 %x, %y Previously, only signed comparisons were being handled. Decrements could also be handled, but 'sub nuw %x, 1' is currently canonicalized to 'add %x, -1' in InstCombineAddSub, losing the nuw flag. Removing that canonicalization seems like it might have far-reaching ramifications so I kept this simple for now. Patch by Matti Niemenmaa!
