JDK 9 RFR of JDK-8078467: Update core libraries to use diamond with anonymous classes

[joe darcy]

Hello,

Earlier in JDK 9, the diamond syntax was expanded to be usable with many 
cases of anonymous classes. [1]

Please review the fix below take advantage of the new syntax (and also 
take advantage of the original diamond syntax in some cases) in the core 
libraries:

     JDK-8078467: Update core libraries to use diamond with anonymous 
classes
     http://cr.openjdk.java.net/~darcy/8078467.0/

The main beneficiary of the new syntax are call sites of PrivilegedAction.

Follow-up bugs also filed for security libs (JDK-8078468) and 
java.util.concurrent (JDK-8078469).

Thanks,

-Joe
