Serguei Katkov 522b9cfa46 [Test] Add a unit test exposing lack of SCEV invalidation in LICM during code hoisting. NFC.
This unit test exposes a bug in LICM: when it hoists instructions it doesn't invalidate SCEV accordingly.
Similar test exposing lack of SCEV invalidation during code sinking will be submitted as a follow-up change.
