Indicate the slow path of `Check_Type` never return [Bug #18062]
Though this call to `rb_check_type` is just to raise an exception and never return actually, it can return at least formally. That means a caller function looks like it will access `flags` even in the special-const cases, and some optimizers may unify the access with the same access just following the call, and re-order it before the guard.
