@sarnex,
IMHO, the implementation of `CC_DeviceKernel` case should look like:
```c++
case CC_DeviceKernel:
return CGM.getTargetCodeGenInfo().getDeviceKernelCallingConv();
```
SPIR/SPIR-V/NVPTX/AMDGPU targets should define target specific calling
convention.
i.e. getOpenCLKernelCallingConv -> getDeviceKernelCallingConv.
