Unrolled build for rust-lang#140351

Rollup merge of rust-lang#140351 - rust-lang:notriddle/stability-use, r=thomcc

docs: fix incorrect stability markers on `std::{todo, matches}`

This regression appeared in 916cfbc. The change is behaving as expected (a non-glob re-export uses the stability marker on the `use` item, not the original one), but this part of the standard library didn't follow it.

Fixes rust-lang#140344
