a2e40fbd62 Add EH support to the MCJIT.
This gets exception handling working on ELF and Macho (x86-64 at least).
Other than the EH frame registration, this patch also implements support
for GOT relocations which are used to locate the personality function on
MachO.

0e1327e4aa This exposes more MCJIT options via the C API:
CodeModel: It's now possible to create an MCJIT instance with any CodeModel you like.  Previously it was only possible to 
create an MCJIT that used CodeModel::JITDefault.

EnableFastISel: It's now possible to turn on the fast instruction selector.

The CodeModel option required some trickery.  The problem is that previously, we were ensuring future binary compatibility in 
the MCJITCompilerOptions by mandating that the user bzero's the options struct and passes the sizeof() that he saw; the 
bindings then bzero the remaining bits.  This works great but assumes that the bitwise zero equivalent of any field is a 
sensible default value.

But this is not the case for LLVMCodeModel, or its internal equivalent, llvm::CodeModel::Model.  In both of those, the default 
for a JIT is CodeModel::JITDefault (or LLVMCodeModelJITDefault), which is not bitwise zero.

Hence this change introduces LLVMInitializeMCJITCompilerOptions(), which will initialize the user's options struct with
defaults. The user will use this in the same way that they would have previously used memset() or bzero(). MCJITCAPITest.cpp
illustrates the change, as does the comment in ExecutionEngine.h.

0b8c9a80f2 Move all of the header files which are involved in modelling the LLVM IR
into their new header subdirectory: include/llvm/IR. This matches the
directory structure of lib, and begins to correct a long standing point
of file layout clutter in LLVM.

There are still more header files to move here, but I wanted to handle
them in separate commits to make tracking what files make sense at each
layer easier.

The only really questionable files here are the target intrinsic
tablegen files. But that's a battle I'd rather not fight today.

I've updated both CMake and Makefile build systems (I think, and my
tests think, but I may have missed something).

I've also re-sorted the includes throughout the project. I'll be
committing updates to Clang, DragonEgg, and Polly momentarily.

a1514e24cc Sort includes for all of the .h files under the 'lib' tree. These were
missed in the first pass because the script didn't yet handle include
guards.

Note that the script is now able to handle all of these headers without
manual edits. =]

d04a8d4b33 Use the new script to sort the includes of every file under lib.
Sooooo many of these had incorrect or strange main module includes.
I have manually inspected all of these, and fixed the main module
include to be the nearest plausible thing I could find. If you own or
care about any of these source files, I encourage you to take some time
and check that these edits were sensible. I can't have broken anything
(I strictly added headers, and reordered them, never removed), but they
may not be the headers you'd really like to identify as containing the
API being implemented.

Many forward declarations and missing includes were added to a header
files to allow them to parse cleanly when included first. The main
module rule does in fact have its merits. =]

776054dd93 Add interface for object-based JIT events.
This patch adds the interface to expose events from MCJIT when an object is emitted or freed and implements the MCJIT functionality to send those events.  The IntelJITEventListener implementation is left empty for now.  It will be fleshed out in a future patch.

28989889bf Add a method to indicate section address re-assignment is finished.
Prior to this patch RuntimeDyld attempted to re-apply relocations every time reassignSectionAddress was called (via MCJIT::mapSectionAddress).  In addition to being inefficient and redundant, this led to a problem when a section was temporarily moved too far away from another section with a relative relocation referencing the section being moved.  To fix this, I'm adding a new method (finalizeObject) which the client can call to indicate that it is finished rearranging section addresses so the relocations can safely be applied.

068c65b22d Added LLIMCJITMemoryManager to the lli. This manager will be used for MCJIT instead of DefaultJIMMemoryManager.
It's more flexible for MCJIT tasks, in addition it's provides a invalidation instruction cache for code sections which will be used before JIT code will be executed.

0e4fa5ff36 Re-factored RuntimeDyLd:
1. The main works will made in the RuntimeDyLdImpl with uses the ObjectFile class. RuntimeDyLdMachO and RuntimeDyLdELF now only parses relocations and resolve it. This is allows to make improvements of the RuntimeDyLd more easily. In addition the support for COFF can be easily added.

2. Added ARM relocations to RuntimeDyLdELF.

3. Added support for stub functions for the ARM, allowing to do a long branch.

4. Added support for external functions that are not loaded from the object files, but can be loaded from external libraries. Now MCJIT can correctly execute the code containing the printf, putc, and etc.

5. The sections emitted instead functions, thanks Jim Grosbach. MemoryManager.startFunctionBody() and MemoryManager.endFunctionBody() have been removed.
6. MCJITMemoryManager.allocateDataSection() and MCJITMemoryManager. allocateCodeSection() used JMM->allocateSpace() instead of JMM->allocateCodeSection() and JMM->allocateDataSection(), because I got an error: "Cannot allocate an allocated block!" with object file contains more than one code or data sections.

(and hopefully on Windows). The bots have been down most of the day
because of this, and it's not clear to me what all will be required to
fix it.

The commits started with r153205, then r153207, r153208, and r153221.
The first commit seems to be the real culprit, but I couldn't revert
a smaller number of patches.

When resubmitting, r153207 and r153208 should be folded into r153205,
they were simple build fixes.

61425c0a7f MCJIT support for non-function sections.
Move to a by-section allocation and relocation scheme. This allows
better support for sections which do not contain externally visible
symbols.

Flesh out the relocation address vs. local storage address separation a
bit more as well. Remote process JITs use this to tell the relocation
resolution code where the code will live when it executes.

The startFunctionBody/endFunctionBody interfaces to the JIT and the
memory manager are deprecated. They'll stick around for as long as the
old JIT does, but the MCJIT doesn't use them anymore.

afe153c53f Fixed the MCJIT so that it can emit not only instance
methods but also class methods for Objective-C.

Clang emits Objective-C method names with '\1' at the
beginning, and the JIT has pre-existing logic to try
prepending a '\1' when searching a module for an
instance method (that is, a method whose name begins
with '-').  I simply extended it to do the same thing
when it encountered a class method (a method whose
name begins with '+').
