This is needed if we compile StdlibUnittest with -sil-serialize-all So far I added the imports only in files which needed them. But this may change, depending on the optimizer (inlining). Adding them in all files doesn't harm and avoids confusion if someone makes an unrelated change which would result in such a linker error.
