Optimize for the most common cases of `format!`

Format specs are ignored and not stored in case they're all default.
Restore default formatting parameters during iteration.
Pass `None` instead of empty slices of format specs to take advantage
of non-nullable pointer optimization.

Generate a call to one of two functions of `fmt::Argument`.
