<pre>I'm actually going to keep this one open to track the work needed to enable
TailDuplicate in the NVPTX target.
Currently gated on 17876.
The other main issue with TailDuplicate is that it can duplicate barriers in
bad ways. Though rare, this can be a correctness issue. This needs to be
addressed.</pre>
