https://github.com/openjdk/jdk/blob/3ac91b08cbe16bc1a347178f853513f930ffeaf3/src/hotspot/share/cds/heapShared.cpp

heapShared.cpp is getting too big and contains two distinct group of functions:

- reading/writing the archive heap at the object level
- loading the archive heap into memory, at the region level

For better maintenance, the latter part should be moved to a new file archiveHeapLoader.cpp
