This change adds support for the CIRGlobalValueInterface and attributes for visibility and comdat to GlobalOp. The comdat attribute isn't correctly calculated yet, but it was required for the CIRGlobalValueInterface interface. There are also some cases where dso_local isn't set correctly, but it is better than it was before this change. Those issues will be addressed in a future patch.
