Tool to peek into CDS archive

[Ashutosh Mehra]

Hi Calvin,

Thanks for the option. "-XX:+PrintSharedArchiveAndExit" is what I was
looking for.
btw it looks like the PrintSharedDictionary flag is redundant, I guess
PrintSharedArchiveAndExit already covers it.
I don't see PrintSharedDictionary being checked anywhere in the code base.

Regards,
Ashutosh Mehra
