----------------
This feature is header only. We had a lot of discussions on that and the main idea was not to declare header only features/extensions in `OpenCLExtensions.def` and use `-D__opencl_c_atomic_scope_all_devices=1` instead, @Anastasia can comment on this.

I personally would like to introduce new flag for OpenCL options in `OpenCLExtensions.def` which will indicate that feature/extension is header-only, and thus all of such options can be declared in `OpenCLExtensions.def`: if flag is set to true it can be stripped out from the parser. What do you think about this?
