d50dfdb399 8054402: "klass->is_loader_alive(_is_alive)) failed: must be alive" for anonymous classes 
Because anonymous classes are not in the system dictionary, we have to set 'unloading_occurred' based on 'CLDG::do_unloading()'. Added jtreg test.

cafb36661d 8003426: Remove UseFastAccessors and UseFastEmptyMethods except for zero 
These options have been long disabled in Xmixed mode because they prevent these small methods from being inlined and are subject to bit rot, and we don't need more macro assembler code to maintain and change if the constant pool cache format changes.
