For this [test case](https://godbolt.org/z/v3GGf9aqb):
```
int cudaLaunchKernel();
__global__ void fn() {}
int main() {
fn<<<1, 1>>>();
}
```
Clang would crash when compiled with `--cuda-host-only`. The reason is that `emitDeviceStubBodyNew` retrieves the type `dim3` by looking into the second argument of `cudaLaunchKernel`, which does not exist in this case.
