*) Indent breaks:

  61   case T_BOOLEAN: __ load_unsigned_byte(dst, src); break;
  62   case T_BYTE:    __ load_signed_byte(dst, src); break;
  63   case T_CHAR:    __ load_unsigned_short(dst, src); break;
  64   case T_SHORT:   __ load_signed_short(dst, src); break;
  65   case T_INT:     __ movl  (dst, src); break;
  66   case T_ADDRESS: __ movptr(dst, src); break;

*) It looks like {c|i|d|f}aloads are missing IN_HEAP_ARRAY decorators

*) The uncommented RB in ShenandoahBarrierSetAssembler::load_at -- had we missed it before? If so,
should it be done separately to land in sh/jdk10 too?

*) Ditto for uncommented WB in  ShenandoahBarrierSetAssembler::store_at?
