OnDiskCache
provides an interface to incr. comp. data cached from the
previous compilation session. This data will eventually include the results
of a few selected queries (like typeck_tables_of
and mir_optimized
) and
any diagnostics that have been emitted during a query.

Store a diagnostic emitted during computation of an anonymous query.
Since many anonymous queries can share the same DepNode
, we aggregate
them -- as opposed to regular queries where we assume that there is a
1:1 relationship between query-key and DepNode
.
