Reduce the use of metaspaceShared.hpp

      Description

      metaspaceShared.hpp is included indirectly into over 500 files due to this single use in oop.inline.hpp

      http://hg.openjdk.java.net/jdk/jdk/file/9c6d5e31618e/src/hotspot/share/oops/oop.inline.hpp#l355

      void oopDesc::forward_to(oop p) {
      ...
        assert(!MetaspaceShared::is_archive_object(oop(this)) &&
               !MetaspaceShared::is_archive_object(p),
               "forwarding archive object");

      The problem is whenever I work on metaspceShared.hpp or compactHashtable.hpp (included by the former), I have to repeatedly compile almost every file.

      The use in oopDesc::forward_to should be refactored to avoid the excessive inclusion.
