V8 recently [imported](https://issues.chromium.org/issues/406357277) the Dragonbox library for double to string conversions: https://github.com/jk-jeon/dragonbox

JSC [started using this](https://github.com/WebKit/WebKit/pull/20467) a few years ago.

We're currently using Google's double-conversion library (it's in MFBT) that's based on code in V8.  Dragonbox is not a complete replacement for all conversions, but it should be faster for the typical double to string conversion.

Thanks to Mayank for pointing us to the V8 change.

We're currently using Google's double-conversion library (it's in MFBT) that's based on code in V8.  Dragonbox is not a complete replacement for all conversions (IIRC at least `Number.prototype.toFixed` isn't supported), but it should be faster for the typical double to string conversion.
