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.
