Describe the bug

#include <memory>
#include <execution>
#include <vector>

int32_t
main()
{
  std::vector<int> v(10);
  auto first = v.begin();
  auto itr = ::cuda::counting_iterator<std::vector<int>::iterator>(first);
  return 0;
}

How to Reproduce

nvc++ -stdpar --c++17 test.cpp

Expected behavior

For the test to compile fine after the fix.

@zkhatami This is not a bug but a missing include of <cuda/__iterator/counting_iterator.h>, what algorithm are you trying to run?

[zkhatami]

That's right. Then we need to address it in our compiler. I'll close the bug then.
