I'm seeing an internal compiler error on the following input, found by fuzz-rustc:

Code

extern {
    async fn L() {
        async fn M() {}
    }
}

Error output

Note that this code should not compile, the two errors before the ICE are correct.
Affected versions: nightly 2022-04-07 and beta 1.61.0-beta.1 both ICE with the same message, stable 1.60 does not ICE.

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.62.0-nightly (e745b4ddb 2022-04-07) running on x86_64-unknown-linux-gnu

note: compiler flags: --crate-type lib -C embed-bitcode=no -C codegen-units=1 -C debuginfo=2

note: some of the compiler flags provided by cargo are hidden

query stack during panic:
end of query stack
thread panicked while panicking. aborting.
error: could not compile `playground` due to 2 previous errors

The error message is the same as #95307, but this issue looks more similar to #91370.
