Mark Simulacrum a689b2d8ac Rollup merge of #51312 - frewsxcv:clarify-hash-map-entry-get-mut, r=dtolnay ...

Clarify the difference between get_mut and into_mut for OccupiedEntry

The examples for both hash_map::OccupiedEntry::get_mut and
hash_map::OccupiedEntry::into_mut were almost identical. This led to some
confusion over the difference, namely why you would ever use get_mut when
into_mut gives alonger lifetime. Reddit thread:
https://www.reddit.com/r/rust/comments/8a5swr/why_does_hashmaps

This commit adds two lines and a comment to the example, to show that the
entry object can be re-used after calling get_mut.
