RFR: 8247466: AIX link error undefined MetaspaceShared::_use_optimized_module_handling

[Ioi Lam]

Hi Matthias,

I think this should be fixed by JDK-8247388, which has been integrated 
into the jdk15 repo (and should be synced to jdk/jdk soon).

http://hg.openjdk.java.net/jdk/jdk15/rev/a7ad60e19730

It has the same changes in arguments.cpp as in your version.

I think your changes in systemDictionary.cpp is not necessary, because 
the function is already enclosed in INCLUDE_CDS. Also, the change in 
filemap.cpp is not necessary because this file is omitted when CDS is 
not enabled.

If JDK-8247388 indeed fixes the AIX build, please close JDK-8247466 as a 
duplicate.

Thanks
- Ioi
