ValueOwnershipKindClassifierandOperandOwnershipKindClassifiershould have the same classification forautodiff_function_extract.ValueOwnershipKindClassifier's classification was fixed by #27199, which gave the correct ownership verification results. Now we fix it inOperandOwnershipKindClassifier.DifferentiableFunctionExtractOriginalExpr's SILGen is now corrected to borrowing the argument and emitting a copy for the extracted original function.
