Clang compiler error with named parallel_reduce, tags, and TeamPolicy.

[mrtupek]

The following code compiles with gcc, intel, nvcc, but not clang (3.6 and 3.8):

struct Foo {

struct MyTag {
};

void compute() {
double totalEnergy = 0.0;
Kokkos::parallel_reduce("name", Kokkos::TeamPolicy(100, Kokkos::AUTO), *this, totalEnergy);
}

KOKKOS_INLINE_FUNCTION void operator() (const MyTag&, const Kokkos::TeamPolicy::member_type& team, double& val) const {
int index = team.league_rank();
val += index;
}

};

int main(int argc, char* argv[]) {

Kokkos::initialize(argc, argv);

Foo foo;
foo.compute();

Kokkos::finalize();

}

This was incidentally fixed by the parallel_reduce implementation changes I worked on.
