Alex Crichton c07ec507e2 rollup merge of #22287: Ryman/purge_carthographers
This overlaps with #22276 (I left make check running overnight) but covers a number of additional cases and has a few rewrites where the clones are not even necessary.

This also implements `RandomAccessIterator` for `iter::Cloned`

cc @steveklabnik, you may want to glance at this before #22281 gets the bors treatment
