---------------------------
cpu: Allow setWhen on trace objects

Allow setting of 'when' in trace records.  This allows later times
than the arbitrary record creation point to be used as inst. times

I am fine with the patch as such.  Can you explain what is arbitrary about
the tick recorded in the InstRecord as of now?

Having the tick value in the InstRecord be ‘correct’ is useful if you want to do side-by-side timing comparisons with another CPU model.  This could have been done with some side structure, adding debugging output, or by adding an extra timing value (or two) to InstRecord but it seemed easiest to repurpose ‘when’ on InstRecord.

You have a pending review.
