I know this steps a little out from the code you're changing, but it would be a nice cleanup (https://llvm.org/docs/CodingStandards.html#don-t-use-else-after-a-return).
```suggestion
  if (CGF.getLangOpts().HLSL && Ops.Ty->hasFloatingRepresentation())
    return Builder.CreateFRem(Ops.LHS, Ops.RHS, "rem");
