Clippy: backport ICE fix before beta branch

r? `@Manishearth`

Before beta is branched tomorrow we should backport the fix from https://github.com/rust-lang/rust-clippy/pull/10027 for an ICE. That way we'll get this into stable one release sooner.

This only cherry-picks the fix, not the tests for it. The proper sync of this will be done next week Thursday.
