LGTM.

File src/compiler/graph-visualizer.cc (right):

https://codereview.chromium.org/523593002/diff/1/src/compiler/graph-visualize...
src/compiler/graph-visualizer.cc:213: << (NodeProperties::IsControlEdge(edge) ?
"style=dashed" : "")
suggestion: As discussed offline, it might make sense to flip the styles of
control-edges and context-edges. To me the most important edges are the
control-edges most of the time, so intuitively it makes sense to me to have them
be bold.
