miri no longer builds after rust-lang/rust#66275

[rust-highfive]

Hello, this is your friendly neighborhood mergebot.
After merging PR #66275, I observed that the tool miri has failing tests.
A follow-up PR to the repository https://github.com/rust-lang/miri is needed to fix the fallout.

cc @oli-obk, do you think you would have time to do the follow-up work?
If so, that would be great!

cc @RalfJung, the PR reviewer, and nominating for compiler team prioritization.

The error is

error: internal compiler error: src/librustc_typeck/collect.rs:1869: to get the signature of a closure, use `closure_sig()` not `fn_sig()`

with the following backtrace

Ah but further up the call stack we have

so I think this will be fixed by #66866
