Properly test internal headers (NVIDIA#1258)
Browse files Browse the repository at this point in the history
* Add tests for internal headers, so that we know that they do not rely on transitive includes
* Add tests for fallback definitions of traits, to ensure hat all fallbacks are functional
* Add tests that all public headers can be included
* Add tests that all public headers can be included by just a host compiler
