It used to be there to workaround the absence of compiler-rt that should be provided by us on those systems, as required by LLVM. We haven't started to provide that, as far as I know, but I guess maybe LLVM doesn't require it anymore? |

I believe LLVM has started supporting it natively, but I'm not 100% sure. |

I believe this code existed to work around bugs that LLVM used to have with 128 bit numbers on 32 bit systems, but I'm not entirely sure.
