Added a test infrastructure that simulates eclipse with diet-parse, type-binding and so forth. Similar to eclipse, the test needs to be executed with lombok as vm-agent. @Delegate runs with this setup, sadly val does not, at least for now.

And as expected the tests shows that @Synchronized and @SneakyThrows are currently broken for eclipse but not for ecj.
