Break apart erlang:load_module/2 into two separate BIFs
Introduce two new BIFs, erlang:prepare_loading/2 and
erlang:finish_loading/1, and re-implement erlang:load_module/2 in
Erlang code.
We have two reasons for doing this:
* To facilitate suspending a process if another process
is already doing code loading.
* In the future, we can implement parallel and atomic loading
of several modules. Atomic loading works except for modules with
on_load handlers. Because of that issue, erlang:finish_loading/2
will currently only accept a list with a single magic binary.
