a50e7bd0a6 Correct MCJIT functionality for MIPS32 architecture. 
No new tests are added.
All tests in ExecutionEngine/MCJIT that have been failing pass after this patch
is applied (when "make check" is done on a mips board). 

Patch by Petar Jovanovic.

e52a5ca15b 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.

79c030996a Remove getElfArchType from ELF.h. It's only used in ELFObjectFile.cpp and there's already a copy there. ELF.h was hiding the one there and causing an unused function warning.

6e9bcca355 This patch improves the MCJIT runtime dynamic loader by adding new handling 
of zero-initialized sections, virtual sections and common symbols
and preventing the loading of sections which are not required for
execution such as debug information.

d29d7cfe60 Support reading GNU symbol versions in ELFObjectFile 
* Add enums and structures for GNU version information.
* Implement extraction of that information on a per-symbol basis (ELFObjectFile::getSymbolVersion).
* Implement a generic interface, GetELFSymbolVersion(), for getting the symbol version from the ObjectFile (hides the templating).
* Have llvm-readobj print out the version, when available.
* Add a test for the new feature: readobj-elf-versioning.test

44201a2d17 [Object] 
* Add begin_dynamic_table() / end_dynamic_table() private interface to ELFObjectFile.
* Add begin_libraries_needed() / end_libraries_needed() interface to ObjectFile, for grabbing the list of needed libraries for a shared object or dynamic executable.
* Implement this new interface completely for ELF, leave stubs for COFF and MachO.
* Add 'llvm-readobj' tool for dumping ObjectFile information.

e9705e2949 [Object] Add symbol attribute flags: ST_ThreadLocal, ST_Common, and ST_Undefined. Implement these completely for ELF. 
Rename ST_External to ST_Unknown, and slightly change its semantics. It now only indicates that the symbol's type
is unknown, not that the symbol is undefined. (For that, use ST_Undefined).

ff2a79674c Expose the ELFObjectFile class directly in the Object/ELF.h header, similarly 
to what's done for MachO and COFF. This allows advanced uses of the class to
be implemented outside the Object library. In particular, the DyldELFObject
subclass is now moved into its logical home - ExecutionEngine/RuntimeDyld.

This patch was reviewed by Michael Spencer.
