One of the pieces of feedback that was regrettably blocking https://gerrit.lix.systems/c/lix/+/2975 is that adding a pile of bit builtins would further fill up the builtins namespace. Secondly we have a problem where builtins should really only be used by nixpkgs lib, at least for new builtins that should be used through a polyfill.

For example, we could have builtins.bit.bitShiftLeft.

I don't know how to force the second, but we probably want the capability to namespace builtins anyhow. Maybe builtins.privateForNixpkgsLibUseOnly or something, which requires this anyway.
