This new version includes a fix for building on aarch64 windows.
WebAssembly supports saturating floating point to integer casts behind a target feature. The feature is already available on many browsers. Beginning with 1.45 Rust will start defining the behavior of floating point to integer casts to be saturating as well. For this Rust constructs additional checks on top of the `fptoui` / `fptosi` instructions it emits. Here we introduce the possibility for the codegen backend to construct saturating casts itself and only fall back to constructing the checks ourselves if that is not possible.
This commit modifies resolve to disallow `break`/`continue` to labels through closures or async blocks. This doesn't make sense and should have been prohibited anyway. Signed-off-by: David Wood <david@davidtw.co>

…k-through-closure-async, r=petrochenkov resolve: disallow labelled breaks/continues through closures/async blocks Fixes rust-lang#73541. This PR modifies name resolution to prohibit labelled breaks/continues through closures or async blocks, fixing an ICE. In addition, it improves the diagnostics surrounding labelled breaks/continues through closures or async blocks by informing the user if the label exists in an parent scope and telling them that won't work. r? @petrochenkov (resolve) cc @estebank (diagnostic changes) @tmandry (issue is from `wg-async-foundations`)
…earth Use 'tcx for references to AccessLevels wherever possible. Most of the changes are just fallout from removing a lifetime parameter from structs, and mostly in clippy. r? @Manishearth
Update psm version This new version includes a fix for building on aarch64 windows. cc rust-lang#72881
Add option for local docker testing. This adds the option `--dev` to `src/ci/docker/run.sh` so that it will enter an interactive environment for local testing. I have often needed this for testing things, but I always needed to edit this script. I wanted the ability to interact in the environment, run different commands, inspect errors, etc.
disable BTree min_max test in Miri for now Until rust-lang#73915 is fixed, better skip this test in Miri so that we can test the others at least.
