Expand description

Misc info we load from metadata to persist beyond the tcx.

Note: though CrateNum is only meaningful within the same tcx, information within CrateInfo is self-contained. CrateNum can be viewed as a unique identifier within a CrateInfo, where used_crate_source contains all CrateSource of the dependents, and maintains a mapping from identifiers (CrateNum) to CrateSource. The other fields map CrateNum to the crate’s own additional properties, so that effectively we can retrieve each dependent crate’s CrateSource and the corresponding properties without referencing information outside of a CrateInfo.
