Static analyzers say these are unused:

class ShenandoahBarrierSet: public BarrierSet {
  enum ArrayCopyStoreValMode {

    template <class T> void
  write_ref_array_pre_work(T* src, T* dst, size_t count, bool dest_uninitialized);

Their last use was before JDK-8231086 landed. We can remove this cruft now.
Fix Request (11u) Same reason, applicability, results as for 15u backport.

Fix Request (15u) This simplifies Shenandoah maintainability and provides the ground for subsequent backports. Patch applies cleanly to 15u, passes hotspot_gc_shenandoah, tier{1,2} with Shenandoah enabled. Patch is completely isolated in Shenandoah code.
