Auto merge of #38017 - arthurprs:hm-extend, r=bluss
Smarter HashMap/HashSet pre-allocation for extend/from_iter HashMap/HashSet from_iter and extend are making totally different assumptions. A more balanced decision may allocate half the lower hint (rounding up). For "well defined" iterators this effectively limits the worst case to two resizes (the initial reserve + one resize). cc #36579 cc @bluss
