Summary: AttributeList::get(Fn|Ret|Param)Attributes no longer creates a temporary AttributeList just to hide the AttributeSetNode type. I've also added a factory method to create AttributeLists from a parallel array of AttributeSetNodes. I think this simplifies construction of AttributeLists when rewriting function prototypes. Previously we would test if a particular index had attributes, and conditionally add a temporary attribute list to a vector. Now the attribute set vector is parallel to the argument vector already that these passes already construct. My long term vision is to wrap AttributeSetNode* inside an AttributeSet type that holds the enum attributes, but that will come in a follow up change. I haven't done any performance measurements for this change because profiling hasn't shown that any of the affected code is hot.
