Make expansions stable for incr. comp. This PR aims to make expansions stable for incr. comp. by using the same architecture as definitions: - the interned identifier `ExpnId` contains a `CrateNum` and a crate-local id; - bidirectional maps `ExpnHash <-> ExpnId` are setup; - incr. comp. on-disk cache saves and reconstructs expansions using their `ExpnHash`. I tried to use as many `LocalExpnId` as I could in the resolver code, but I may have missed a few opportunities. All this will allow to use an `ExpnId` as a query key, and to force this query without recomputing caller queries. For instance, this will be used to implement #85999. r? `@petrochenkov` |
