Seems you are just creating debug info based on the original function and sharing that with the continuations / splits? Or perhaps just 'CoroDebugInfo'?

Good call @TylerNowicki! I like 'common', updated the stack accordingly. 

It was originally "global" in a sense that it was owned by a module (global) rather than the function (local) and so didn't have to be cloned as part of function cloning. But I agree that it can be confusing this way.
