The current reduction tries all or nothing elimination of named metadata. I noticed in one case where one of the module flags was necessary, but it left the rest. Reduce the individual operands of named metadata nodes that are known to behave like lists. Be conservative since some named metadata may have more specific verifier requirements for the operands.
