F896811: simplifycfg_expensive - perf.csv <http://reviews.llvm.org/F896811>

This data comes from the same system and has the same baseline as before (r248957) but reverts r248439, so if there are expensive ops (div/rem) that can be speculatively executed and folded into selects, this data should show the perf effect.

But again, I don't see any differences.
