I don't see anything adding or using parameters here.  I also don't know how you'd use a parameter you added this way in the builtin call params you pass in (how do you reference it to create the DeclRefExpr?).

Since this part is unused, should we really be adding it at this time?  Could we add it when it's used to make sure it's working as intended?
