[NVPTX] Annotate convergent intrinsics as convergent.

Authored by jlebar on Feb 16 2016, 5:03 PM.



Previously the machine instructions for bar.sync &co. were not marked as
convergent. This resulted in some MI passes (such as TailDuplication,
fixed in an upcoming patch) doing unsafe things to these instructions.
