As the "LLVMInitializeAll*" functions are not available as symbols in
the shared library they can't be used, and as a workaround a list of
the targets is kept and the individual symbols tried. As soon as the
"All"-functions are changed to proper symbols (as opposed to static
inlines in the headers) this hack will be replace with simple calls
to the corresponding "LLVMInitializeAll*" functions.

This is a part of a series of patches that have been sitting fallow on a
personal branch that I have been messing with for a bit.
The patches start to flesh out the python llvm-c wrapper to the point where you can:
1. Load Modules from Bitcode/Dump/Print them.
2. Iterate over Functions from those modules/get their names/dump them.
3. Iterate over the BasicBlocks from said function/get the BB's name/dump it.
4. Iterate over the Instructions in said BasicBlocks/get the instructions
name/dump the instruction.
My main interest in developing this was to be able to gather statistics about
LLVM IR using python scripts to speed up statistical profiling of different IR
level transformations (hence the focus on printing/dumping/getting names).
This is a gift from me to the LLVM community = ).
I am going to be committing the patches slowly over the next bit as I have time
to prepare the patches.
The overall organization follows the c-api like the bindings that are already
implemented.

Before this fix, the LLVM Python bindings on SVN trunk always fail with:
Exception: LLVM shared library not found!
since it's still looking for a library named "LLVM-3.1svn".
Besides updating the LLVM version in the library name,
this patch also changes llvm.get_library() to make it possible to run
the unit tests without installing the LLVM shared library into a
default linker search path.
e.g. after this patch, running the llvm/python unit tests with:
LD_LIBRARY_PATH=../build/Debug+Asserts/lib nosetests -v bindings/python/llvm/tests/
would work on Linux.

Adds /usr/lib/debug early to list, as some systems (debian) have unstripped libs in there
Adds /lib/i386-linux-gnu for systems that does multiarch (debian)

Chris Lattner says the edis interface is going away. It doesn't make
sense to land something that will go away in the near future.

This requires a C++ change to EDDisassembler's ctor to function properly
(the llvm::InitializeAll* functions aren't being called currently and
there is no way to call them from Python).
Code is partially tested and works well enough for initial commit. There
are probably many small bugs.

It is now possible to load object files and scan over sections, symbols,
and relocations! Includes test code with partial coverage.

This contains a semi-functional skeleton for the implementation of the
LLVM bindings for Python.
The API for the Object.h interface is roughly designed but not
implemented. MemoryBufferRef is implemented and actually appears to
work!
The ObjectFile unit test fails with a segmentation fault because the
LLVM library isn't being properly initialized. The build system doesn't
know about this code yet, so no alerts should fire.
