JDK 10 RFR of JDK-8173383: Update JDK build to use -source and -target 10

[David Holmes]

Hi Joe,

Changes look okay. So does javac already handle arbitrary source/target 
values?

We need the usual set of "new release" updates to change JDK version as 
well. Where does that hide these days ??

And do we also need to update the boot JDK to be JDK 9?

What else is needed for a new release to start? We really should have 
all this captured in a single bug report.

Also wondering if JPRT will need any updates ...

Thanks,
David
