Hi,
Newer compilers are not happy with arraycopy since recent changes made RawAccessBarrier accept 5 arguments instead of 3, and there was an unused path in Access for HeapWord* arraycopy, that was not expanded, that still tried to call an internal arraycopy function with 3 arguments.
The problematic unexpanded overload in RawAccessBarrier for HeapWord* addresses has been removed. Instead, the HeapWord logic for performing Raw oop arraycopy when it is not known whether compressed oops is used or not has been moved to an earlier stage (reduce_types) to better reflect how this logic is consistently handled for the other accessors with the same HeapWord* logic, to make the code more symmetric.

Thanks, /Erik
