Craig Topper a4e47586b9 [ExpandMemCmp] Recognize canonical form of (icmp sle/sge X, 0) in getMemCmpOneBlock. (#121540) ...

This code recognizes special cases where the result of memcmp is
compared with 0. If the compare is sle/sge, then InstCombine
canonicalizes to (icmp slt X, 1) or (icmp sgt X, -1). We should
recognize those patterns too.
