[PATCH] D18458: [CUDA] Mangle __host__ __device__ functions differently than __host__ or __device__ functions.

rsmith added a comment.

It seems like we have the following constraint: on host, no attributes must mangle the same as `__host__ __device__` and `constexpr` (and probably `__global__`?).

Are there any others? What do we need to do to be ABI-compatible with NVCC? (And is that possible if we allow `__host__` to overload `__host__ __device__`?)

One possibility given only that constraint would be to use a different mangling for H functions and D functions, but mangle HD and unattributed functions the same.
