Just a general note (not related to this change specifically): In the introduction (`llvm/docs/QualGroup.rst`), we mention ISO 26262, DO-178C, and EN 50128. Since EN 50128 has been withdrawn and superseded by EN 50716, and given that IEC 61508 (parent standard) and IEC 62304 (medical devices) are also relevant, would it make sense to update/extend that list?
