Module rustc_incremental::persist::dirty_clean

Debugging code to test fingerprints computed for query results. For each node marked with #[rustc_clean] we will compare the fingerprint from the current and from the previous compilation session as appropriate:

• #[rustc_clean(cfg="rev2", except="typeck")] if we are in #[cfg(rev2)], then the fingerprints associated with DepNode::typeck(X) must be DIFFERENT (X is the DefId of the current node).
• #[rustc_clean(cfg="rev2")] same as above, except that the fingerprints must be the SAME (along with all other fingerprints).

Errors are reported if we are in the suitable configuration but the required condition is not met.
