These operations are much more about lowering the HIR than about `Const`s themselves. They fit better in hir_ty_lowering with `lower_const_arg` (formerly `Const::from_const_arg`) and the rest. To accomplish this, `const_evaluatable_predicates_of` had to be changed to not use `from_anon_const` anymore. Instead of visiting the HIR and lowering anon consts on the fly, it now visits the `rustc_middle::ty` data structures instead and directly looks for `UnevaluatedConst`s. This approach was proposed in: https://github.com/rust-lang/rust/pull/131081#discussion_r1821189257
