344be5fbec Tests of the ocaml (and thus C) bindings for constants.

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.

6e19896999 Objective-C was generating EH frame info like this: 
"_-[NSString(local) isNullOrNil]".eh = 0
        .no_dead_strip  "_-[NSString(local) isNullOrNil]".eh

The ".eh" should be inside the quotes.

8c33da5dc4 Fix for PR1633: Verifier doesn't fully verify GC intrinsics 
LLVM now enforces the following prototypes for the write barriers:

<ty>* @llvm.gcread(<ty2>*, <ty>**)
void @llvm.gcwrite(<ty>*, <ty2>*, <ty>**)

And for @llvm.gcroot, the first stack slot is verified to be an alloca or a 
bitcast of an alloca.

Fixes test/CodeGen/Generic/GC/lower_gcroot.ll, which violated these.
