[OCaml] Update core test and re-enable testing

[jketema]

Summary

Update the OCaml core test to use the current IR syntax in its check lines. Also drop the creation of debug meta-data, as this is currently not supported by the C interface.

Just remove this too. I don't think version 2 is even readable by LLVM anymore...

I updated this to version 3 instead, as this is the only test for named meta-data, and I prefer not to loose that test.
