LGTM with a nit.



================
Comment at: llvm/lib/Target/NVPTX/NVPTXAsmPrinter.cpp:432-436
+          uint64_t Count =
+              mdconst::extract<ConstantInt>(UnrollCountMD->getOperand(1))
+                  ->getZExtValue();
+          if (Count == 1)
+            return true;
----------------
This all can be folded directly into 
`if (mdconst::extract<ConstantInt>(UnrollCountMD->getOperand(1))->getZExtValue() == 1) return true;`
