[PATCH] D119965: [LICM][PhaseOrder] Don't speculate in LICM until after running loop rotate

[Dávid Bolvanský via Phabricator via llvm-commits]

Last I saw, GVNHoist was disabled due to perf regressions. Then, new effort started to reimplement it - https://lists.llvm.org/pipermail/llvm-dev/2021-September/152665.html but somehow dead now.

So you may improve your specific loop with GVNHoist, but you will something else.
