Description

Since IR node attributes must all inherit from AstAttribute we need to write wrappers around POD types and 3rd party types when we want to store them as IR attributes. We've ended up with a proliferation of such attributes that all do almost the same thing but have different names to access their data members. Hopefully by providing one class template we can avoid further proliferation.
