RFR: 8261455: Automatically generate the CDS archive if necessary

[Yumin Qi]

Please review,
  When shared archive (dynamic archive) failed to map due to damage of the archive file, dump/run jdk version mismatch or non-existence file etc, the new patch will automatically create a new shared archive if -XX:+AutoCreateSharedArchive specified with the name based on SharedArchiveFile.
  This is a revised patch based on the old PR: 5077 and after bug 8273152 integrated.

Tests: tier1,tier2,tier3,tier4

Thanks
Yumin
