            * config/rs6000/rs6000-builtins.def
            (__builtin_vsx_scalar_cmp_exp_qp_eq_kf): Rename KFmode comparison
            built-in functions to have a KF suffix to allow overloading.
            (__builtin_vsx_scalar_cmp_exp_qp_gt_kf): Likewise.
            (__builtin_vsx_scalar_cmp_exp_qp_lt_kf): Likewise.
            (__builtin_vsx_scalar_cmp_exp_qp_unordered_kf): Likewise.
            (__builtin_vsx_scalar_cmp_exp_qp_eq_tf): Add TFmode comparison
            built-in functions.
            (__builtin_vsx_scalar_cmp_exp_qp_gt_tf): Likewise.
            (__builtin_vsx_scalar_cmp_exp_qp_lt_tf): Likewise.
            (__builtin_vsx_scalar_cmp_exp_qp_unordered_tf): Likewise.
            * config/rs6000/rs6000-overload.def
            (__builtin_vec_scalar_cmp_exp_eq): Add TFmode overloaded
            functions.
            (__builtin_vec_scalar_cmp_exp_gt): Likewise.
            (__builtin_vec_scalar_cmp_exp_lt): Likewise.
            (__builtin_vec_scalar_cmp_exp_unordered): Likewise.
