This tool lets us build LLVM components within the tree by setting up a
$GOPATH that resembles a tree fetched in the normal way with "go get".
It is intended that components such as the Go frontend will be built in-tree
using this tool.

Merges equivalent loads on both sides of a hammock/diamond
and hoists into into the header.
Merges equivalent stores on both sides of a hammock/diamond
and sinks it to the footer.
Can enable if conversion and tolerate better load misses
and store operand latencies.

Patch by Gabriel Radanne.
While this commit technically breaks API, no code should have supplied
the integer IDs directly, and thus no code should break.

The returnvalue was handled as c_char_p which ment that ctypes
handled it as a NUL-terminated string making it cut the contents
at first NUL (or even worse - overrunning the buffer if it doesn't
contain a NUL).

We normally don't drop functions from the C API's, but in this case I think we
can:
* The old implementation of getFileOffset was fairly broken
* The introduction of LLVMGetSymbolFileOffset was itself a C api breaking
change as it removed LLVMGetSymbolOffset.
* It is an incredibly specialized use case. The only reason MCJIT needs it is
because of its odd position of being a dynamic linker of .o files.

This commit embeds a set of linker flags with hardcoded paths to
the LLVM shared library on --enable-shared builds into .cmxa files
and stub dynamic libraries. This solution closely follows existing
rules for rpath in the LLVM tools, which had to be modified because
of differences in toolchain.
Without this patch, OCaml tests as well as opam bindings broke,
as neither of those updates LD_LIBRARY_PATH to include
the $prefix/lib directory.

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 allows to only link in the needed targets, reducing binary
size and more importantly link time.
Note that this is an incomplete implementation: currently,
LLVM does not have the plumbing which would allow to conditionally
link in AsmPrinter, AsmParser and Disassembler for the targets
which support them. This should be improved in the future.

This commit significantly speeds up both bytecode and native
builds of LLVM clients (from ~20 second to sub-second link time),
and allows to invoke LLVM functions from OCaml toplevel.
The behavior for --disable-shared builds is unchanged.

Llvm_target.intptr_type used to implicitly use global context. As
none of other functions in OCaml bindings do, it is changed to
accept context explicitly.

This commit only changes comments and documentation in OCaml bindings. The official name of the language is OCaml, and the usage is now consistent.

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.

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.

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.
