Chandler Carruth 219b89b987 [Modules] Move CallSite into the IR library where it belogs. It is 
abstracting between a CallInst and an InvokeInst, both of which are IR
concepts.

Chandler Carruth 8394857f43 [Modules] Move InstIterator out of the Support library, where it had no 
business.

This header includes Function and BasicBlock and directly uses the
interfaces of both classes. It has to do with the IR, it even has that
in the name. =] Put it in the library it belongs to.

This is one step toward making LLVM's Support library survive a C++
modules bootstrap.

Reid Kleckner 26af2cae05 Update optimization passes to handle inalloca arguments 
Summary:
I searched Transforms/ and Analysis/ for 'ByVal' and updated those call
sites to check for inalloca if appropriate.

I added tests for any change that would allow an optimization to fire on
inalloca.

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 c1b648f6c0 [objc-arc] Fix assertion in EraseInstruction so that noop on null calls when passed null do not trigger the assert. 
The specific case of interest is when objc_retainBlock is passed null.

Michael Gottesman 3b8f877860 Add clang.arc.used to ModuleHasARC so ARC always runs if said call is present in a module. 
clang.arc.used is an interesting call for ARC since ObjCARCContract
needs to run to remove said intrinsic to avoid a linker error (since the
call does not exist).

Michael Gottesman 49f9885a2a Non optimizable objc_retainBlock calls are not forwarding. 
Since we handle optimizable objc_retainBlocks through strength reduction
in OptimizableIndividualCalls, we know that all code after that point
will only see non-optimizable objc_retainBlock calls. IsForwarding is
only called by functions after that point, so it is ok to just classify
objc_retainBlock as non-forwarding.

Michael Gottesman 65c2481d09 Changed isNullOrUndef => IsNullOrUndef and isNoopInstruction => IsNoopInstruction so that all helper functions are named similarly in ObjCARC.h.

Michael Gottesman 23a1ee5f5b Fixed some whitespace/80+ violations. Also added a space after a namespace declaration.

Michael Gottesman 13a5f1a8b7 Juggled Debug.h from ObjCARC.h to only the including cpp files that 
actually have DEBUG statements. Also changed raw_ostream in said header
to be a forward declaration (removing an include).

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.

Michael Gottesman 08904e3ba4 Extracted pass ObjCARCExpand from ObjCARC.cpp => ObjCARCExpand.cpp. 
I also added the local header ObjCARC.h for common functions used by the
various passes.
