As used in RFC 1574: https://github.com/rust-lang/rfcs/blob/master/text/1574-more-api-documentation-conventions.md#using-markdown

"Safety" is used many times more than "Unsafety" is within existing docs.

Deny the `overflowing_literals` lint for all editions

The `overflowing_literals` was made deny by default for the 2018 edition by #54507, however I'm not aware of any reason it can't be made deny by default for the 2015 edition as well.

31eb0e2d3c Auto merge of #57609 - matthewjasper:more-restrictive-match, r=pnkfelix 
Use normal mutable borrows in matches

`ref mut` borrows are currently two-phase with NLL enabled. This changes them to be proper mutable borrows. To accommodate this, first the position of fake borrows is changed:

```text
[ 1. Pre-match ]
       |
[ (old create fake borrows) ]
[ 2. Discriminant testing -- check discriminants ] <-+
       |                                             |
       | (once a specific arm is chosen)             |
       |                                             |
[ (old read fake borrows) ]                          |
[ 3. Create "guard bindings" for arm ]               |
[ (create fake borrows) ]                            |
       |                                             |
[ 4. Execute guard code ]                            |
[ (read fake borrows) ] --(guard is false)-----------+
       |
       | (guard results in true)
       |
[ 5. Create real bindings and execute arm ]
       |
[ Exit match ]
```

The following additional changes are made to accommodate `ref mut` bindings:

* We no longer create fake `Shared` borrows. These borrows are no longer needed for soundness, just to avoid some arguably strange cases.
* `Shallow` borrows no longer conflict with existing borrows, avoiding conflicting access between the guard borrow access and the `ref mut` borrow.

There is some further clean up done in this PR:

* Avoid the "later used here" note for Shallow borrows (since it's not relevant with the message provided)
* Make any use of a two-phase borrow activate it.
* Simplify the cleanup_post_borrowck passes into a single pass.
