5133 - show instruction source in trace

It's a little hacky in some corner cases. In particular, if debug information
isn't available the trace will contain duplicated lines. This is because
I don't want the core trace lines all my tests rely on (introduced in the
'vm' layer) to have to know about debug info (introduced in the 'labels'
and 'debug' layers).

Thanks Charles Saternos for the feedback and suggestion!
