The idea is to use `-emit-gpu-object` and `-emit-gpu-bundle` instead of the
`-f[no-]gpu-bundle-device-output`. Otherwise they'd do exactly the same thing.
I think `-emit-gpu-{object,bundle}` has a minor edge over
`-f[no-]gpu-bundle-device-output` as it's similar to other -emit options for
controlling clang compilation phases (and that's what we want to do here),
while `-f` options are usually for tweaking code generation.
