> Backporting JDK-8328107: Shenandoah/C2: TestVerifyLoopOptimizations test failure. Addresses failure found when running `compiler/loopopts/TestVerifyLoopOptimizations.java` test with Shenandoah GC. Fix replaces CountedLoop with a Loop node when a load barrier is expanded on the backedge of the counted loop. Adds test to confirm expected behavior. Ran GHA Sanity Checks, local Tier 1 and 2 tests. Patch is clean.
