Aaron Hill 5580e5e1dd Ensure that Fingerprint caching respects hashing configuration ... Fixes #92266 In some `HashStable` impls, we use a cache to avoid re-computing the same `Fingerprint` from the same structure (e.g. an `AdtDef`). However, the `StableHashingContext` used can be configured to perform hashing in different ways (e.g. skipping `Span`s). This configuration information is not included in the cache key, which will cause an incorrect `Fingerprint` to be used if we hash the same structure with different `StableHashingContext` settings. To fix this, the configuration settings of `StableHashingContext` are split out into a separate `HashingControls` struct. This struct is used as part of the cache key, ensuring that our caches always produce the correct result for the given settings. With this in place, we now turn off `Span` hashing during the entire process of computing the hash included in legacy symbols. This current has no effect, but will matter when a future PR starts hashing more `Span`s that we currently skip.		2022-01-05 10:13:28 -05:00
