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.

8008199: Lazy compilation and trampoline implementation
Summary: The code pipeline now supports lazy compilation, which can be used to only compile certain FunctionNodes and leave others be, saving startup time. When these uncompiled nodes are hit, a trampoline will force them to be recompiled. This can also be used to specialize compilation fixing parameter types and return types to a callsite specific compilation. This will give performance.
