> This patch optimizes String.format expressions that uses trivial specifiers. In the JDK, the most common variation of String.format is a variation of format("foo: %s", s), which gets a significant speed-up from this.
>
> Various other cleanups and minor improvements reduce overhead further and ensure we get a small gain also for more complex format strings.
