5f5c28bf63 8061391: concat as a builtin optimistic form, had to remove NoTypedArrayData and replace it, as we throw away a lot of optimistic link opportunities with NoTypedArrayData not being Continuous

fab85d4210 8012518: Reengineer Parser.java to make it play well with the copy-on-write IR 
Remove the kludges introduced to make the parser work with the copy on write IR. Now everything is done bottom up, finshing node children completely before node parents. The repeated non-functional pattern 'node = node.setSomething(something);' is gone. Resulting code is much more readable, and extensible for future work. The parser is now also consistent with the rest of the stateless copy-on-write world in code generation.

187399b1fd 8040102: Remove all references to Unsafe and definition of anonymous clases from the code 
As the catch combinator optimization is now part of java.lang.invoke we don't need to put our own in the boot class path in any configuration anymore. Furthermore, with the completion of the array performance subtask of optimistic typing, we can remove the experimental (commented out) Unsafe accessors in the ArrayData classes

f6722c9a3f 8038406: Testability: as a first step of moving loggers away from the process global space, the Debug object now supports logging POJOs from log entries as an event queue, which can be introspected from test scripts. This is way better than screen scraping brittle and subject-to-change log output

76bde64811 8037177: -Dnashorn.optimistic should be enabled by default, meaning that it has to be explicitly set to false to run with the jdk 8 style conservative types 
This will be the new default setting, so the explicit flag should be removed, and instead reverse checked for explicitly DISABLED optimistic types. In the future, we might remove the flag altogether.

9d927196e8 8036127: Prototype filter needs to be applied to getter guard as well, not just getter 
This manifests itself as a bug in optimistic types, as inner functions may access properties of the wrong type, but it is also a bug in tip. Without optimistic types, we have been unable to find a reproducer due to more similar PropertyMaps
