   if (llvm::Function *atexitFn = dyn_cast<llvm::Function>(atexit.getCallee()))

Thanks for pointing this out. I believe this is a bug. I was supposed to only let `Local` in `unregisterGlobalDtorWithUnAtExit` as default value `false`. Because it is only used in relation to Windows.

Since we are already under the context that `XLCXXABI` is an AIX C++ ABI, I kinda feel it's a duplication to add OS check.
