Hm! I actually thought we optimized ShenandoahHeap::heap() enough not to matter [1]. Reverting
heap() cache would seem to ditch some of these overloads:

 131   inline ShenandoahEvacOOMScope();
 132   inline ShenandoahEvacOOMScope(Thread* t);
 133   inline ShenandoahEvacOOMScope(ShenandoahHeap* heap);
 134   inline ShenandoahEvacOOMScope(ShenandoahHeap* heap, Thread* t);
 135   inline ~ShenandoahEvacOOMScope();

Thread:current() seems fine to pass, where available, and store locally.
