RFR: 8243287: Removal of Unsafe::defineAnonymousClass

[Brian Goetz]

There may be some JDK code that checks for anon classes by comparing the name to see if it contains a slash, especially tests, but which don’t say “anonymous”.  Did you do a search for these idioms too, which are now dead tests?

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.
