[aarch64-port-dev ] RFR: 8144993: Elide redundant memory barrier after AllocationNode

[Vitaly Davidovich]

Yes that was my fault; I had forgotten about the ArgEscape analysis result.

To answer your question somewhat, if an object is NoEscape then it's scalar
replaced in the end.  I don't think there's any other end result in hotspot
(e.g there's no stack allocation).
