Threads in the native or blocked states don't prevent safepoints, so they may run concurrently with a safepoint operation like GC. It is not safe for handles to be allocated while the GC is visiting them, so these threads must not allocate handles. Assert only threads in the VM or generated states, which prevent safepoints until they check in, may allocate handles. (Generated code does not allocate handles, but leaf runtime entries remain in the generated state.)

In order to simplify testing and performance comparison, it is useful to
be able to run a command-line VM with a Dart source and use bytecode pipeline.
The bytecode generation is turned on in kernel service if --enable-interpreter
or --use-bytecode-compiler VM option is specified.
