6964458: Reimplement class meta-data storage to use native memory
Remove PermGen, allocate meta-data in metaspace linked to class loaders, rewrite GC walking, rewrite and rename metadata to be C++ classes Co-authored-by: Stefan Karlsson <stefan.karlsson@oracle.com> Co-authored-by: Mikael Gerdin <mikael.gerdin@oracle.com> Co-authored-by: Tom Rodriguez <tom.rodriguez@oracle.com> Reviewed-by: jmasa, stefank, never, coleenp, kvn, brutisso, mgerdin, dholmes, jrose, twisti, roland
