Auto merge of #104688 - flip1995:clippyup, r=Manishearth,flip1995
Update Clippy

r? `@Manishearth`

Sorry for taking so long. There were so many blockers and so little time. This situation should be mitigated with #104007 in the future.

-### What it does
-Checks for loops which have a range bound that is a mutable variable
-
-### Why is this bad?
-One might think that modifying the mutable variable changes the loop bounds
-
-### Known problems
-False positive when mutation is followed by a `break`, but the `break` is not immediately
-after the mutation:
-
-```
-let mut x = 5;
-for _ in 0..x {
-    x += 1; // x is a range bound that is mutated
-    ..; // some other expression
-    break; // leaves the loop, so mutation is not an issue
-}
-```
-
-False positive on nested loops ([#6072](https://github.com/rust-lang/rust-clippy/issues/6072))
-
-### Example
-```
-let mut foo = 42;
-for i in 0..foo {
-    foo -= 1;
-    println!("{}", i); // prints numbers from 0 to 42, not 0 to 21
-}
-```
