We don't need it any more, and removing it simplifies a few things: - One fewer predefined `File` and reserved ID. - We now have simply `Builtin` instructions for builtins, instead of having an `ImportRef` that indirectly references a `Builtin`. - `ConstantId`s now always refer directly to a local constant, instead of sometimes referring to an `ImportRef` for a constant in the builtins IR. --------- Co-authored-by: Jon Ross-Perkins <jperkins@google.com>
