`matches` is ambiguous

I feel like we've seen this before, but filing since it looks like it's occurring again in 1.94.

Start with the linked crater logs, especially the api_call.rs:23 diagnostic and the util/compat/macros.rs definition, then trace how the std::prelude::v1::* import creates the ambiguity. Done means the reported crates no longer hit the matches ambiguity or related panic under Rust 1.94.
