Remove virtual from destructors of copyable classes. A class that is copyable or copy-assignable should never be virtual, because any subclass will be subject to the slicing problem. Use '= default' anytime we just want the default implementation. Writing out the list of member fields by hand is error-prone. Signed-off-by: Jeremy Nimmer <jeremy.nimmer@tri.global>
