      After the fix for JDK-8319372, which removed some better type information for CastIINode, we might be able to relax the added bailout constraint !n->is_Type(). This RFE should investigate if that's possible.

      We should be careful about sinking CheckCastPPNodes which, however, should be fine after the fix for JDK-8276064. But we should double-check that.
