[ARC] Pull the ObjC ARC components that really serve the role of

analyses into LLVM's Analysis library rather than having them in
a Transforms library.

This is motivated by the need to have the core AliasAnalysis
infrastructure be aware of the ObjCARCAliasAnalysis. However, it also
seems like a nice and clean separation. Everything was very easy to move
and this doesn't create much clutter in the analysis library IMO.
