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.

9889ab1f60 Remove reliance on const_trait in sort implementations 
const_trait in conjunction with specialization was
deemed not ready for usage in this scenario. So
instead a two-stage trait specialization approach
is used. This approach is likely worse for
compile-times. Future work that enables
const_trait can revert back to the previous
version as outlined in the comment marked
FIXME(effects).

Simplify `try_*`'s signature on `Iterator`

Inspired by https://github.com/rust-lang/rust/pull/126249#issuecomment-2161859295.

r? `@scottmcm`

(Seems there's no need to explicitly use `<Self as Iterator>::Item`? I only find this occurrence across the whole file.)

d1414c5e0d Rollup merge of #126242 - yaahc:simplify-provider, r=jhpratt 
Simplify provider api to improve llvm ir

This PR seeks to resolve the last concern in https://github.com/rust-lang/rust/issues/99301#issuecomment-1699427740

We resolve the issue by moving the type_id to be stored in the `Request` itself rather than being accessed through the `Erased` trait, letting the compiler infer that the value of the type id will not change between lookups.
