Please review the restructuring and cleanup of java heap object 
archiving code. The java object archiving code has grown in the past 
year and metaspaceShared.* files are not the suitable place. The 
restructuring and cleanup include:

   - Moved java heap object archiving implementation from 
metaspaceShared.* to heapShared.*.
   - Various is_archive_object() APIs are renamed to 
is_archived_object() for naming consistency:
      - Renamed MetaspaceShared::is_archive_object() to 
      - Renamed oopDesc::is_archive_object() to 
      - Renamed G1ArchiveAllocator::is_archive_object() to 
   - Changed to use G1ArchiveAllocator::is_archived_object() in 
G1CollectedHeap::materialize_archived_object(). Removed #include 
"memory/metaspaceShared.inline.hpp” from g1CollectedHeap.cpp.
   - Renamed HeapShared::archive_static_fields() to
