Following commit 401dd84 in the Rust project

(https://github.com/rust-lang/rust),
`ErrorGuaranteed` was replaced by fatal errors.
As a result, `tcx.analysis()` now aborts directly
instead of returning an error guard.
To accommodate this change, this update replaces
`tcx.analysis()` with `typeck()`
to perform type checking in the example.
