It seems like this is trying to hide some algorithmic problem in the pass.
I think we should try to fix the pass instead. @trentxintong can you provide such cases?

The reason why I say this is that we sprinkled cutoffs over the optimizer and some of them have bitten us back. Given that CallSiteSplitting is a relatively new pass (and a clean/simple one), maybe there's something we can try before giving up.
