`max_size()` currently checks if the allocator's `max_size() <= numeric_limits<size_type>::max() / 2`, but then subtracts an alignment, causing an overflow for values less than the alignment. We should probably just diagnose when the `max_size()` of the allocator is so small that our string implementation is just broken (e.g. `max_size() < SSO size`).
