Clarify that "keep_infinity" compress option is only useful for older versions of Chrome. The initial performance assessment that concluded `Infinity` was faster than `1/0` was based on Chrome 57. mishoo#1723 (comment) Chrome 63 suffers no such degradation. https://jsperf.com/infinity-vs-1-0-v2-0

There was a problem hiding this comment.
It would be better to state when Chrome reached performance parity for 1/0 and Infinity. If not the specific version, at least the year.

Not that having more options is bad, but does anyone out there actually switches this on? |

I noticed @std/esm was using keep_infinity which initially sparked my
