Motivation for this change

I recalled this when the old machine got back in Hydra :-) but it won't hurt to fix this in any case.

Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Ensured that relevant documentation is up to date
  • Fits CONTRIBUTING.md.

The uops-CMOV16rm-noreg.s doesn't exist on LLVM 8 and earlier and I can't see those touched in the previous PR, so I hope those are OK.

I couldn't bear watching the failures for long :-)
