Hasher used to determine if two diagnostics are the same and should be deduplicated. Used by DiagCtxtInner::emitted_diagnostics. It’s a stable hash with one special behaviour: parents of spans within the diagnostics are ignored so that incremental and non-incremental compilation get the same behaviour.
