This changes the OCaml toplevel to be a lazy value, which is only forced when needed to run tests in an OCaml block. The motivation behind this change is to avoid stderr output from the init process (e.g., errors while registering pretty-printers) spilling into the test executable's output, which can trip up some build tools.
