Any users of -liv-reduce?

Are people actively using the -liv-reduce option?

See IndVarSimplify.cpp:

static cl::opt<bool> ReduceLiveIVs("liv-reduce", cl::Hidden,
   cl::desc("Reduce live induction variables."));

-liv-reduce is an off-by-default internal option that splits
<op>.with.overflow intrinsics into arithmetic and explicit overflow
checks, so that SCEV can widen and optimize these. After two recent
changes [0], "-liv-reduce" should no longer be necessary for SCEV to
recognize and optimize overflow intrinsics, so I'd prefer to remove it
unless there are people who actively depend on it.
