Apply noundef attribute to &T, &mut T, Box<T>, bool
This doesn't handle `char` because it's a bit awkward to distinguish it from u32 at this point in codegen. Note that for some types (like `&Struct` and `&mut Struct`), we already apply `dereferenceable`, which implies `noundef`, so the IR does not change.
