Eli Bendersky fc079081b7 RuntimeDyld code cleanup:
- There's no point having a different type for the local and global symbol
  tables.
- Renamed SymbolTable to GlobalSymbolTable to clarify the intention
- Improved const correctness where relevant

Preston Gurd cc31af9328 Implement GDB integration for source level debugging of code JITed using
the MCJIT execution engine.

The GDB JIT debugging integration support works by registering a loaded
object image with a pre-defined function that GDB will monitor if GDB
is attached. GDB integration support is implemented for ELF only at this
time. This integration requires GDB version 7.0 or newer.

Patch by Andy Kaylor!

Danil Malyshev 70d22ccb22 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.

Chandler Carruth e26dafeb79 Revert a series of commits to MCJIT to get the build working in CMake
(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.

Eli Bendersky 058d647adf Split the lib/ExecutionEngine/RuntimeDyld/RuntimeDyldImpl.h header to smaller logical headers.
ELF and MachO implementations of RuntimeDyldImpl go into their own header files now.
