Added `-x cuda`. The test is to show we don't get an error 
(`err_drv_unsupported_opt_for_target`) when compiling for x86_64 using a device 
(AMDGPU/NVPTX) when certain target-specified options are specified.

I am not familiar with offloading but specifying `--cuda-host-only` would 
defeat the purpose.

Offloading compilation for these single-source languages pretty much just 
combines one "host" compilation job with N "Device" compilation jobs. Doing 
`--offload-device-only` and `--offload-host-only` simply does one part of that. 
There's probably some flags that behave differently depending on which end 
you're compiling on, so maybe it would be useful for separating that behavior 
if needed.
