Update the standard library to Rust 2024 #138162

ehuss · 2025-03-07T14:09:33Z

This updates the standard library to Rust 2024. This includes the following notable changes:

Macros are updated to use new expression fragment specifiers. This PR includes a test to illustrate the changes, primarily allowing const {...} expressions now.
Some tests show a change in MIR drop order. We do not believe this will be an observable change (see zulip discussion).

cc @rust-lang/libs-api for the macro :expr upgrade -- while I understand the need for an edition boundary, I think this perfectly safe for macros we control, and should be a strict upgrade. Feel free to take API control of the review if needed, otherwise it looks good to me!
