Michael Gottesman 6eb95dc2f7 [objc-arc] Changed 'mode: c++' => 'C++' at Nick Lewycky's suggestion. Also removed unnecessary mode: c++ lines from .cpp files.

Michael Gottesman a72630d453 [objc-arc] Teach the ARC optimizer that objc_sync_enter/objc_sync_exit do not modify the ref count of an objc object and additionally are inert for modref purposes.

Michael Gottesman cd4de0f9bb [ObjCARC Annotations] Added support for displaying the state of pointers at the bottom/top of BBs of the ARC dataflow analysis for both bottomup and topdown analyses.
This will allow for verification and analysis of the merge function of
the data flow analyses in the ARC optimizer.

The actual implementation of this feature is by introducing calls to
the functions llvm.arc.annotation.{bottomup,topdown}.{bbstart,bbend}
which are only declared. Each such call takes in a pointer to a global
with the same name as the pointer whose provenance is being tracked and
a pointer whose name is one of our Sequence states and points to a
string that contains the same name.

To ensure that the optimizer does not consider these annotations in any
way, I made it so that the annotations are considered to be of IC_None
type.

A test case is included for this commit and the previous
ObjCARCAnnotation commit.

Michael Gottesman 778138e960 Extracted ObjCARCContract from ObjCARCOpts into its own file.
This also required adding 2x headers Dependency Analysis.h/Provenance Analysis.h
and a .cpp file DependencyAnalysis.cpp to unentangle the dependencies inbetween
ObjCARCContract and ObjCARCOpts.

Michael Gottesman 5ed40afe17 Created ObjCARCUtil.cpp for functions which in my humble opinion are too large to static inline and place in a header file such as ObjCARC.h.
