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).
