[Clang] Convergent Attribute

[Anastasia Stulova via cfe-commits]

> CUDA? In any case, I don't see how the restriction helps users, and the attribute at the IR level has a well-defined meaning regardless. If a user were to have a use case, they'd simply find the restriction arbitrary and frustrating.

Yes, CUDA was already considered as well. I just think that compilers should help to reduce amount of erroneous or meaningless use cases. That's one of the reasons to have language options for the attributes. But I don't feel strongly about this particular case anyways. So let's make it language independent then. ;)
