Are there any tests that can be enabled now for the optional parameter handling?

I had to implement support for optional parameters, because FindCodeObject
requires it. For now, it is only running in unchecked mode. Besides
FindCodeObject, there are many tests for optional parameters, however, it is
still too early to enable them. My goal is to make sure all vm tests pass before
I enable the Dart tests.
