Auto merge of #83314 - Aaron1011:print-unstable-value, r=lcnr
Debug-print result when an unstable fingerprint is detected Helps with issues like #83311 I had previously tried to do this in https://github.com/rust-lang/rust/pull/80692, but it had a significant performance impact (even though the code was never actually run). Hopefully, this will be better now that https://github.com/rust-lang/rust/pull/79100 has been merged.
