Begin the painful process of tearing apart the rat'ss nest that is Constants.cpp and ConstantFold.cpp.
This involves temporarily hard wiring some parts to use the global context.  This isn't ideal, but it's
the only way I could figure out to make this process vaguely incremental.

Add a pointer to the owning LLVMContext to Module.  This requires threading LLVMContext through a lot
of the bitcode reader and ASM parser APIs, as well as supporting it in all of the tools.

Patches for Clang and LLVM-GCC to follow.

While I'm here, alphabetize.

string::find returns string::npos if the substring is not found.

Add lto_codegen_set_assembler_path() API which allows the linker to specify the
path to the assembler tool to run.  When assembler is used (instead of compiler)
different command line options are used.
Add LTO_API_VERSION #define so clients (linkers) can conditionalize use of new APIs.

llvm-svn: 72823

Move setRelocationModel() to be called before TargetMachine is instantiated.

 - This matches llvm-ld.

It took a bit of archeology to figure out what the right thing to do was
(whether this was intentionally added or intentionally removed). My final
conclusion is that Chris added this intentionally here:
  http://llvm.org/viewvc/llvm-project?view=rev&revision=16913
but the changes weren't propogated to llvm-ld until here:
  http://llvm.org/viewvc/llvm-project?view=rev&revision=34058
which was after lto.cpp had been cloned off (of llvm-ld), here:
  http://llvm.org/viewvc/llvm-project?view=rev&revision=29494

From the commit message, it looks like the motivation for running global opt
again is because we ran it prior to inlining. Based on that I updated the
comment and also only run the pass if we actually ran the inliner.

Chris, please review.

 - I know it sounds crazy, but I think all the pass lists are now coalesced into
   StandardPasses.h.

Also, alter mangler so that objc method names are readable.

Wire this up to the gold plugin. You can now pass --plugin-opt gcc=/foo/bar/gcc
and it will run that gcc instead of looking for it on the path.

The debugger sometimes lookup dynamically in the runtime to find ivar info of any Objective-C classes. It would be very helpful to debugger if the compiler encodes runtime version number in DWARF.

Add support for two additional DWARF attributes to encode Objective-C runtime version number.
