When a thread stops on an abort frame, the recognizer will unwind the stack to
look for the frame from which the assert was triggered.
Once located, it will set this frame as the current one and change the stop
reason.

To do so, the StackFrameRecognizer class holds a "Most Relevant Frame" and a
StopInfo attribute. When the thread is about to stop, it checks if the
current frame is recognized, and if so, it fetches the recognized frame's
attributes and applies them.
