bors 0250ff9a5f Auto merge of #22681 - mzabaluev:extend-faster, r=huonw
Instead of a fast branch with a sized iterator falling back to a potentially poorly optimized iterate-and-push loop, a single efficient loop can serve all cases.

In my benchmark runs, I see some good gains, but also some regressions, possibly due to different inlining choices by the compiler. YMMV.
