RFR: 8243287: Removal of Unsafe::defineAnonymousClass [v2]

[Harold Seigel]

> Please review this large change to remove Unsafe::defineAnonymousClass().  The change removes dAC relevant code and changes a lot of tests.  Many of the changed tests need renaming.  I hope to do this in a follow up RFE.  Some of the tests were modified to use hidden classes, others were deleted because either similar hidden classes tests already exist or they tested dAC specific functionality, such as host classes.
> 
> This change was tested with Mach5 tiers 1-2 on Linux, Mac OS, and Windows, and Mach5 tiers 3-7 on Linux x64.

> Thanks, Harold
