Alright. I will add what is required as protected members of CGOpenMPRuntime.
For now I didn't do that for any of the classes given that we are not doing any
actual codegen.

Ok, once we start moving things to `CGOpenMPRntime` runtime, we add this to
CodeGenFunction accordingly.

Ok. I'll do that once we post the codegen patches.

Ok, I did that. Also I added a new diagnostic in the compiler invocation so
that the user gets a message instead of a stack dump. Let me know if you agree.
