f21b1058a1 Add support in the LTO library for loading an object from the middle 
of an file.

38c4e53549 Add a special streamer to libLTO that just records symbols definitions and 
uses.

The result produced by the streamer is used to give the linker more accurate
information and to add to llvm.compiler.used. The second improvement removes
the need for the user to add __attribute__((used)) to functions only used in
inline asm. The first one lets us build firefox with LTO on Darwin :-)

b4cc031a3e Don't open the file again in the gold plugin. To be able to do this, update 
MemoryBuffer::getOpenFile to not close the file descriptor.

cbb170d057 Make it possible to set the target triple and expose that with an option in the 
gold plugin.

e823db8bae Added getDefaultSubtargetFeatures method to SubtargetFeatures class which returns a correct feature string for given triple.

0e7a54672c Maintain the old LTO API, by using the global context.

4434ed44c4 Make the use of const with respect to LLVMContext sane. Hopefully this is the last time, for the 
moment, that I will need to make far-reaching changes.

31895e7359 Hold the LLVMContext by reference rather than by pointer.

8b477ed579 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.

3eb445feb2 <rdar://problem/6927148> libLTO needs to handle i386 magic objc class symbols 
Parse __OBJC data structures and synthesize magic .objc_ symbols.
Also, alter mangler so that objc method names are readable.
