There were basically two bugs here: When C++20 `to_address` is called on `int arr[10]`, then `const _Ptr&` becomes a reference to a const array, and then we dispatch to `__to_address<const int(&)[10]>`, which, oops, gives us a `const int*` result instead of an `int*` result. Solution: We need to provide the two standard-specified overloads of `std::to_address` in exactly the same way that we provide two overloads of `__to_address`. When `__to_address` is called on a pointer type, `__to_address(const _Ptr&)` is disabled so we successfully avoid trying to instantiate pointer_traits of that pointer type. But when it's called on an array type, it's not disabled for array types, so we go ahead and instantiate pointer_traits<int[10]>, which goes boom. Solution: We need to disable `__to_address(const _Ptr&)` for both pointer and array types. Also disable it for function types, so that they get the nice error message; and put a test on it.
