Gordon Henriksen 8ef426baa3 Adding ocaml language bindings for the vmcore and bitwriter libraries. These are
built atop the C language bindings, and user programs can link with them as 
such:

  # Bytecode
  ocamlc -cc g++ llvm.cma llvmbitwriter.cma -o example example.ml
  # Native
  ocamlopt -cc g++ llvm.cmxa llvmbitwriter.cmxa -o example.opt example.ml

The vmcore.ml test exercises most/all of the APIs thus far bound. Unfortunately,
they're not yet numerous enough to write hello world. But:

  $ cat example.ml
  (* example.ml *)
  
  open Llvm
  open Llvm_bitwriter
  
  let _ =
    let filename = Sys.argv.(1) in
    let m = create_module filename in
    
    let v = make_int_constant i32_type 42 false in
    let g = define_global "hello_world" v m in
    
    if not (write_bitcode_file m filename) then exit 1;
    
    dispose_module m;

  $ ocamlc -cc g++ llvm.cma llvm_bitwriter.cma -o example example.ml
  File "example.ml", line 11, characters 6-7:
  Warning Y: unused variable g.
  $ ./example example.bc
  $ llvm-dis < example.bc
  ; ModuleID = '<stdin>'
  @hello_world = global i32 42            ; <i32*> [#uses=0]

The ocaml test cases provide effective tests for the C interfaces.
