* [ARC] Pull the ObjC ARC components that really serve the role ofChandler Carruth2015-08-201-1/+1
| | | | | | | | | | | | | | 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. Differential Revision: http://reviews.llvm.org/D12133 llvm-svn: 245541

| | | | | | | | | | | ptr state change behavior onto a PtrState class. This will enable the main ObjCARCOpts dataflow to work with higher level concepts such as "can this ptr state be modified by this ref count" and not need to understand the nitty gritty details of how that is determined. This makes the dataflow cleaner. llvm-svn: 231437
