Edges are nominally ordered by order in the build manifest, but in fact are ordered by memory address. In most cases the memory address will be monontonically increasing. Since serialized build output will need unique IDs, add a monotonically increasing ID to edges, and use that for sorting instead of memory address.

This is the first commit from #1210 by @colincross cherry-picked on master. I think unique edge IDs are a good idea not only for serialized build output, but for coming up with different build orders, too. Also memory address order isn't reliable.
