* This was mostly for //third_party/nix and its dependencies which now
have been set to use llvmPackages_11 manually.
* For //users/grfn/achilles we also manually select the newer LLVM version.
* //tools/cheddar doesn't seem to need llvm anymore.
* //third_party/buzz also compiles with clang 7.1.0
* replace clang-tools everywhere with new attribute clang-tools_11
For the future we may want to have something similar again, but it may
not be necessary to invest too much time into it: nixpkgs is set to
upgrade their default llvmPackages to LLVM 11 as well at some point in
the near future.
