[NVVM] Remove noduplicate attribute from synchronizing intrinsics.

Authored by jlebar on Mar 14 2016, 5:38 PM.



I've completed my audit of all the code that looks at noduplicate and
added handling of convergent where appropriate, so we no longer need
noduplicate on these intrinsics.

Friendly ping here -- I think we're ready to go with this one. It's necessary to get inlining of functions which contain syncthreads() and unrolling of loops that contain syncthreads(), so has a pretty substantial performance impact.
