Description
The location in the Java heap where the archive heap objects are loaded/mapped is an implementation detail of the GC policy in use. However, when G1 gc is used, the heap location to map archive objects is determined by the CDS.

As a first step towards having a single set of GC APIs to allocate heap for archive objects, the logic to find the heap location for mapping archive objects needs to be moved to G1 GC.

Any idea how do I change its type from "Enhancement" to make it a sub-task of JDK-8296263?
