[PATCH] D84108: [SimplifyCFG][LoopRotate] SimplifyCFG: disable common instruction hoisting by default, enable late in pipeline

[Max Kazantsev via Phabricator via llvm-commits]

mkazantsev added a comment.

I'd suggest splitting this in two parts:

- NFC patch with new options & test updates, but preserving current behavior;
- One-liner patch to switch default values.

This is needed to make revert easier in case if it exposes some problems.
