This PR enables
<cuda/device>APIs to be used on device by calling CUDA device runtime APIs.Once this PR is merged, the user will be able to query:
directly inside a kernel.
This change brings more complexity to our testing, because using CUDA device runtime requires linking
libcudadevrtand separable compilation.For that reason I introduced
WANTS_CUDADEVRT.tag that informslitto linklibcudadevrt.I don't know if
clang-cudasupports linking withlibcudadevrt, will have to find out.
