Adding Ocaml bindings for the bitreader as requested by Sarah
Thompson. Usage should be something like this:
open Llvm
open Llvm_bitreader
match read_bitcode_file fn with
| Bitreader_failure msg ->
prerr_endline msg
| Bitreader_success m ->
...;
dispose_module m
Compile with: ocamlc llvm.cma llvm_bitreader.cma
ocamlopt llvm.cmxa llvm_bitreader.cmxa

+|* Many exotic languages can interoperate with C code but have a harder time *|
+|* with C++ due to name mangling. So in addition to C, this interface enables *|
