f10eae89 - Because all DLLs get initialized before the main module

Because all DLLs get initialized before the main module weak functions are registered after the asan runtime initializes. This means __asan_default_options isn't available during asan runtime initialization. Thus we split asan flag processing into two parts and register a callback for the second part that's executed after __asan_default_options is registered.
