[9] RFR(S): JDK-8039498: Add iterators to GrowableArray

Hi Tobias,

This affects code that is used outside of the compiler so I think you should send it to hotspot-dev at openjdk.java.net for review
We never allocate memory using the default new operator. See src/share/vm/memory/allocation.hpp comment that starts with:

// All classes in the virtual machine must be subclassed
// by one of the following allocation classes:
