Previously we created artifical edges from a LUB node's components to
the LUB node; now the nullability propagation algorithm understands
how to propagate nullability downstream through LUB and substitution
nodes, so no artificial edges are needed.

This gives us more flexibility for how we want to publish and deploy
the tool. We now have the option, for example, of making a command
line app that invokes the tool and does not depend on analysis_server.
Note that some testing infrastructure had to be duplicated. I plan to
consolidate this infrastructure in follow-up CLs.
