Mark de Wever f7c0df002a [libc++][format] Improve format buffer. 
Allow bulk output operations on the buffer instead of adding one
code unit at a time. This has a huge performance benefit at the cost of
larger binary. This doesn't implement @vitaut's earlier suggestion to
avoid buffering for std::string when writing a strings. That can be done
in a follow-up patch.

There are some minor complications for the non-buffered format_to_n.
When writing one character at a time it's easy to detect when reaching
the limit n. This is solved by adding a small overhead for format_to_n.
When the next write would overflow it stores the data in the internal
buffer and copies that up-to n code units. The overhead isn't measured,
but it's expected to only be an issue for small values of n; for larger
values the general improvements will outweight the new overhead.

```

For very small strings the new method is slower, from 4 characters
there's already a small gain.

The int benchmark has benefits for the simple formatting, but shines for
the complex formatting:
