Summary: The AIX linker will produce errors on unresolved weak symbols. Change the generated code to not check for the initialization function but just call it and ensure that it always exists. Also, the AIX atexit routine has a different name (and signature) so call it correctly. Update the lit tests to test on AIX appropriately.
