+ if (!HasNonDeletedCopyOrMoveConstructor()) {

+ return;
----------------
This is not a very useful diagnostic. We have several different reasons why we
reject the attribute, some of which are pretty subtle, and it's not reasonable
to expect users to puzzle it out. At the very least we can tell them the
immediate cause for all of these rejections.
