  Log Message:
  -----------
  [lld][WebAssembly] Create optional internal symbols only after LTO object as been added

This is important for the cases where new symbols can be introduced
during LTO.   Specifically this happens for during TLS-lowering where
references to `__tls_base` can be introduced.
