Rollup merge of #53019 - ljedrz:bad_collects, r=estebank
Don't collect() when size_hint is useless

This adjusts PRs #52738 and #52697 by falling back to calculating capacity and extending or pushing in a loop where `collect()` can't be trusted to calculate the right capacity.

It is a performance win.
