    Add a new traceMarker# primop for use in profiling output
    
    In time-based profiling visualisations (e.g. heap profiles and ThreadScope)
    it would be useful to be able to mark particular points in the execution and
    have those points in time marked in the visualisation.
    
    The traceMarker# primop currently emits an event into the eventlog. In
    principle it could be extended to do something in the heap profiling too.
