fn replace_param_and_infer_args_with_placeholder<'tcx>(
    tcx: TyCtxt<'tcx>,
    args: GenericArgsRef<'tcx>

Replaces args that reference param or infer variables with suitable placeholders. This function is meant to remove these param and infer args when they’re not actually needed to evaluate a constant.
