Code Reloading BIFs

[KronicDeth]

Lumen being Ahead-of-Time compiled will likely never support code reloading, but we may need to stub this out to at least return exceptions or errors with code that expects then to exist.

• [ ] call_on_load_function/1
• [ ] check_old_code/1
• [ ] check_process_code/2
• [ ] check_process_code/3
• [ ] delete_module/1
• [ ] finish_after_on_load/2
• [ ] finish_loading/1
• [ ] has_prepared_code_on_load/1
• [ ] load_module/2
• [ ] loaded/0
• [ ] module_loaded/1
• [ ] pre_loaded/0
• [ ] prepare_loading/2
• [ ] purge_module/1

I think we can probably just stub these out with unimplemented!(), it is safe to abort/panic if these are ever called until we eventually design/build a JIT for Lumen.

erlang:loaded/0 is called in erts/preloaded/src/erl_init.erl
