[PM] Add a really simple trait to the DOTGraphTraitsPass class templates
that lets the analysis and graph types be separate and the graph
computed from the analysis through some arbitrary user-supplied code.
This will allow a call graph to an independent entity from the pass
which creates it which is necessary for the new pass manager.
