Chandler Carruth 0f792189a4 [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.

Michael Gottesman 68b91dbf84 [objc-arc] Extract out state specific to a ref count from the main objc arc sequence dataflow. This will allow me to separate the actual ARC queries from the meat of the dataflow algorithm.

Michael Gottesman 6f729fa675 [objc-arc] Change the InstructionClass to be an enum class called ARCInstKind.
I also renamed ObjCARCUtil.cpp -> ARCInstKind.cpp. That file only contained
items related to ARCInstKind anyways.

Zachary Turner 3bd47cee78 Use ADDITIONAL_HEADER_DIRS in all LLVM CMake projects.
This allows IDEs to recognize the entire set of header files for
each of the core LLVM projects.

Rafael Espindola a3b5b60753 Add back r222061 with a fix.
This adds back r222061, but now calls initializePAEvalPass from the correct
library to avoid link problems.

Original message:

Don't make assumptions about the name of private global variables.

Private variables are can be renamed, so it is not reliable to make
decisions on the name.

The name is also dropped by the assembler before getting to the
linker, so using the name causes a disconnect between how llvm makes a
decision (var name) and how the linker makes a decision (section it is
in).

This patch changes one case where we were looking at the variable name to use
the section instead.

Test tuning by Michael Gottesman.

Reid Kleckner 007239863e Revert "Don't make assumptions about the name of private global variables."
This reverts commit r222061.

It's causing linker errors.

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.
