DIBuilder.InsertValueAtEnd in the Go bindings, to support attaching
debug metadata to register values.

Bindings built out-of-tree, e.g. via OPAM, should append
a line to META.llvm like the following:
linkopts = "-cclib -L$libdir -cclib -Wl,-rpath,$libdir"
where $libdir is the lib/ directory where LLVM libraries are
installed.

Since JIT->MCJIT migration, most of the ExecutionEngine interface
became deprecated and/or broken. This especially affected the OCaml
bindings, as runFunction is no longer available, and unlike in C,
it is not possible to coerce a pointer to a function and call it
in OCaml.
In practice, LLVM 3.5 shipped completely unusable
Llvm_executionengine.
The GenericValue interface and runFunction were essentially
a poor man's FFI. As such, this interface was removed and instead
a dependency on ctypes >=0.3 added, which handled platform-specific
aspects of accessing data and calling functions.
The new interface does not expose JIT (which is a shim around MCJIT),
as well as the interpreter (which can't handle a lot of valid IR).
Llvm_executionengine.add_global_mapping is currently unusable
due to PR20656.

This commit updates the OCaml bindings and tests to use ocamlfind.
The bindings are migrated in order to use ctypes, which are now
required for MCJIT-backed Llvm_executionengine.
The tests are migrated in order to use OUnit and to verify that
the distributed META.llvm allows to build working executables.
Every OCaml toolchain invocation is now chained through ocamlfind,
which (in theory) allows to cross-compile the OCaml bindings.
The configure script now checks for ctypes (>= 0.2.3) and
OUnit (>= 2). The code depending on these libraries will be added
later. The configure script does not check the package versions
in order to keep changes less invasive.
Additionally, OCaml bindings will now be automatically enabled
if ocamlfind is detected on the system, rather than ocamlc, as it
was before.

Pretend they do not exist using exists_if. This is better than
the current situation, which is the error:
Error: The external function `llvm_global_succ' is not available
but still somewhat confusing.

In practice this means:
* Always using -g flag.
* Embedding -cclib -lstdc++ into the corresponding cma/cmxa file.
This also moves -lstdc++ in a single place.
* Using caml_named_value instead of a homegrown mechanism.

First, return true on success, as it is the OCaml convention.
Second, also initialize the native assembly printer, which is,
despite the name, required for MCJIT operation.
Since this function did not initialize the assembly printer earlier
and no function to initialize native assembly printer was available
elsewhere, it is safe to break its interface: it means that it
simply could not be used successfully before.

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

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.

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.

Check should be for pointer being NULL, not what it points to.
Also adds a test for this case.

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 commit brings the module structure, argument order and
primitive names in Llvm_target in order with the rest of the bindings,
in preparation for adding TargetMachine API.

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
