bors e794b0f855 Auto merge of #125720 - folkertdev:optimize_for_size-ptr-rotate, r=Amanieu 
make `ptr::rotate` smaller when using `optimize_for_size`

code to reproduce https://github.com/folkertdev/optimize_for_size-slice-rotate

In the example the size of `.text` goes down from 1624 to 276 bytes.

```
> cargo size --release --features "left-std"  -- -A
