There's already adhoc code for shenandoah in PhaseIdealLoop::build_and_optimize() to replace the missing API call. The backported patch uses the same logic. Tested with tier1 and the patch's test case (fails without the fix, passes with it).

it's good this goes in pair with JDK-8280799. as JDK-8280799 alone can cause a crash on release buidls too.
