Description
When -XX:+UseMembar was taken out serialize_thread_state_with_handler is now the same as serialize_thread_state, and transition_and_fence == transition.

Also clearing unhandled oops is called excessively.
Comments
Further, where we previously needed: set_thread_state(s); serialize_thread_state(thread); because "serializing" was a complex action with three variations, it is now simply a call to fence(). So this can simplify to: set_thread_state_fence(s); with the obvious implementation.
