The tracking issue rust-lang#50264
still has unresolved question for the corresponding `Result` methods.

This is a stylistic change to libstd to reduce the number of checks of

`backtrace` crate and rely on it having an empty implementation.

Still debating if this is the right approach

visit_statement default definition does just this, there's no need to
redefine it.

It has been fully disabled by default since rust-lang#54639.

This commit makes the `improper_ctype` lint trigger for non-exhaustive
types when those types aren't defined in the current crate.
