[turbofan] Also disable concurrent recompilation when tracing TurboFan.

Treat --trace-turbo and --trace-turbo-graph similar to --trace-hydrogen
and --trace-hydrogen-stubs, in that we disable concurrent recompilation
in that case (otherwise we cannot print heap objects and stuff).

Hey Igor,

This makes --trace-turbo and --trace-turbo-graph work again.
Please take a look.

Thanks,
Benedikt
