a scalarized object at a safepoint.
Comments
SUGGESTED FIX Add new ideal node SafePointScalarObjectNode to represent the state of a scalarized object at a safepoint. It describes additional input edges (starting and count) in the safepoint node to which it is attached. SafePointScalarObjectNode nodes will be created for each safepoint nodes which reference the original scalar replaced allocation (this code will be added in next changes).
