Here's one for you:
__host__ float bar();
__device__ int bar();
__host__ __device__ auto foo() -> decltype(bar()) {}
What is the return type of `foo`? :)
I don't believe the right answer is, "float when compiling for host, int when
compiling for device."
I'd be happy if we said this was an error, so long as it's well-defined what
exactly we're disallowing. But I bet @rsmith can come up with substantially
more evil testcases than this.
