This is a continuation of #16863. @lorentey you said you weren't too worried about the FixedWidthInteger._random() implementation as it will soon use the new words initializer™, but I'm simply curious to see if this has any improvements for custom generators in any way. (Can you benchmark?)

Hm, the Linux failure seems unrelated. Let's try again, for luck?
