This picks up a fix in `rustc_apfloat` [1] that resolves a problem with `fma`. [1]: https://github.com/rust-lang/rustc_apfloat/releases/tag/rustc_apfloat-v0.2.3%2Bllvm-462a31f5a5ab
Pick up the latest version of iai-callgrind, which includes some output improvements. Changelog: https://github.com/iai-callgrind/iai-callgrind/releases
This CI workflow will run the https://github.com/rust-lang/josh-sync tool on Mondays and Thursdays. It will try to do a pull (sync stdarch changes from rust-lang/rust into this repository). When it runs, three things can happen: - There are no rustc changes to be pulled, the bot does nothing. - There are some new changes to be pulled. In that case, the bot will either open or update an existing PR titled "Rustc pull update" on this repository with the changes. After the PR is merged, we should ideally do the opposite sync (push) manually. - The pull fails (usually because of a merge conflict), or the bot determines that a pull PR has been opened for more than a week without being merged. In that case, it will post a ping to https://rust-lang.zulipchat.com/#narrow/channel/219381-t-libs/topic/compiler-builtins.20subtree.20sync.20automation/with/528482375.

This is a false positive, see RUST-144060.
Match the new CI-created PRs: rust-lang/compiler-builtins#974.
This alias was added in 9897bfb8a ("Fix memset arguments for MSP430
target"), which predates `core::ffi`. Now that it exists we can just use
`core::ffi::c_int`.
Fix the return type of `memcmp` and `bcmp` builtin functions on targets with a `c_int` other than `i32`. Linked issue: rust-lang#144076
