// The simple answer is to avoid unmaintainable complexity. The reflection
// code assumes ArenaStringPtrs. These are *almost* in-memory-compatible with
// string*, except for the pointer tags and related ownership semantics. We
// could modify the runtime code to use string* for the not-supporting-arenas
// case, but this would require a way to detect which type of class was
// generated (adding overhead and complexity to GeneratedMessageReflection)
// and littering the runtime code paths with conditionals. It's simpler to
// stick with this but use lightweight accessors that assume arena == NULL.
// There should be very little overhead anyway because it's just a tagged
