fingerprintDynFlags :: HscEnv -> Module -> (BinHandle -> Name -> IO ()) -> IO Fingerprint

Produce a fingerprint of a DynFlags value. We only base the finger print on important fields in DynFlags so that the recompilation checker can use this fingerprint.

NB: The Module parameter is the Module recorded by the *interface* file, not the actual Module according to our DynFlags.
