 // unique_ptr-style pointer that stores values that may be from an arena. Takes
 // up the same storage as the platform's native pointer type. Takes ownership
 // of the value it's constructed with; if holding a value in an arena, and the
 // type has a non-trivial destructor, the arena must outlive the
 // QuicArenaScopedPtr. Does not support array overloads.
