Auto merge of #24120 - aturon:range-perf, r=alexcrichton

A recent change to the implementation of range iterators meant that,
even when stepping by 1, the iterators *always* involved checked
arithmetic.

This commit reverts to the earlier behavior (while retaining the
refactoring into traits).

Fixes #24095
Closes #24119
cc #24014
