-debug=3Dd dumps expression DAGS in DOT format.

-debug=3Dv or V produces output on the screen AND also produces
DOT format for the VCG graph(s) alongside the generated .vcg
files.  if you use -debug=3DV and then look at the sequence of generated
graphs in numerical order, you'll see how the VC-generator works!

We have now switched to use "-" on all platforms, so it's best
to use "-" on Windows now...
