rustc_query_system: share previous graph data with current graph
Reduce memory consumption by taking advantage of red/green algorithm properties to share the previous dependency graph's node data with the current graph instead of storing node data redundantly. Red nodes can share the `DepNode`, and green nodes can share the `DepNode` and `Fingerprint`. Edges will be shared when possible in a later change.
