Applied the matcher suggestion and shortened the PR description. I also rebuilt opt and ran the affected test (icmp-srem.ll), check-llvm-transforms-instcombine, and check-llvm-transforms; all passed.

 @dtcxzyw, I don’t have commit access yet. If no further review is needed, would you mind landing this when convenient? Thanks!
