Joerg Sonnenberger 732f95ff9a Reapply r374743 with a fix for the ocaml binding 
Add a pass to lower is.constant and objectsize intrinsics

This pass lowers is.constant and objectsize intrinsics not simplified by
earlier constant folding, i.e. if the object given is not constant or if
not using the optimized pass chain. The result is recursively simplified
and constant conditionals are pruned, so that dead blocks are removed
even for -O0. This allows inline asm blocks with operand constraints to
work all the time.

The new pass replaces the existing lowering in the codegen-prepare pass
and fallbacks in SDAG/GlobalISEL and FastISel. The latter now assert
on the intrinsics.

This directory contains LLVM bindings for the OCaml programming language
(http://ocaml.org).

Prerequisites
-------------

* OCaml 4.00.0+.
* ctypes 0.4+.
* oUnit 2+ (only required for tests).
* CMake (to build LLVM).

Building the bindings
---------------------

If all dependencies are present, the bindings will be built and installed
as a part of the default CMake configuration, with no further action.
They will only work with the specific OCaml compiler detected during the build.

The bindings can also be built out-of-tree, i.e. targeting a preinstalled
LLVM. To do this, configure the LLVM build tree as follows:

    $ cmake -DLLVM_OCAML_OUT_OF_TREE=TRUE \
            -DCMAKE_INSTALL_PREFIX=[OCaml install prefix] \
            [... any other options]

then build and install it as:

    $ make ocaml_all
    $ cmake -P bindings/ocaml/cmake_install.cmake
