regalloc2 upgrade being pulled in somehow with older versions of wasmtime crate

[gamemachine]

Did a cargo update today with no other changes. wasmtime crate is v15. No other bytecodealliance crates. Build failed on cranelift vscode because something is pulling in a newer version of regalloc2. Is something in wasmtime just pulling in the most recent of something? Just guessing.

cc @cfallin and @elliottt, could y'all yank 0.9.4 of regalloc2 and republish it as 0.10.0? Locally I see:

$ cargo install wasmtime-cli@15.0.0
...
error[E0599]: no function or associated item named `forward` found for struct `InstRange` in the current scope
    --> /home/alex/.cargo/registry/src/index.crates.io-6f17d22bba15001f/cranelift-codegen-0.102.1/src/machinst/vcode.rs:1340:20

     |                    ^^^^^^^ function or associated item not found in `InstRange`
     |
note: if you're trying to build a new `InstRange`, consider using `InstRange::new` which returns `InstRange`

and it looks like this method was removed in 0.9.4

Will do, sorry about the trouble!

I've yanked 0.9.4, and will release 0.10.0 on Tuesday. I'll update wasmtime at the same time 👍

With #9193 I'm going to consider this fixed (thanks @elliottt!) and the 0.10.0 upgrade will likely happen today but can be tracked independently of this.
