Expand description

This is the context state available during incr. comp. hashing. It contains enough information to transform DefIds and HirIds into stable DefPaths (i.e., a reference to the TyCtxt) and it holds a few caches for speeding up various things (e.g., each DefId/DefPath is only hashed once).

The krate here is only used for mapping BodyIds to Bodys. Don’t use it for anything else or you’ll run the risk of leaking data out of the tracking system.
