Hmmmm... maybe it was one of my local patches? I'll try to figure out what went
wrong later tonight.

I added logic to be clever about edge types... when splitting an edge, the type
should remain except a forward edge becomes a cross edge. (You can do it out on
paper...) Perhaps that upset things? It doesn't seem like codegen is using
those terms in the usual MST meanings :(
