This test covers the templates which attempt to classify types, but not the actual gathering of arguments of distribution of return values. As before, we can't really use standard C++ to accurately test for HFAs and HVAs, so we stick with approximating them by detecting arrays of the right types. For example, I think technically we should also accept a struct with only 4 float members, but c++ templates aren't able to match against types in that way as far as I know.
