The type inference of argument-position closures and async blocks regressed in 1.70 as the evaluation order of async blocks changed, as they are not implicitly wrapped in an identity-function anymore. Fixes rust-lang#112225 by making sure the evaluation order stays the same as it used to.

stable-nominating because this was injected in 1.70 and seems like it has somewhat unknown scope of impact @rustbot label: +stable-nominated |

As this was a stable-to-stable regression, it might be worth to consider backporting. Although the workaround for this is trivial as well: Just wrap the async block in another block.
