RFR: JDK-8147634 - Need a JImage API that given a JImageLocationRef returns class name

[harold seigel]

Having a range check would be good at least until the switch to using 
indices.

Thanks, Harold

The alternative is to switch to using indices instead of offsets for JImageLocationRef (as I mentioned should have ben done.)  Take a bit of fiddling at this point, but doable.  One would assume that you would guarantee on the result (shut down the vm), since that would mean a fail of the verification data (same as if jimage were invalid.)
