Recurse into function bodies, but don't typeck closures Previously, rustdoc would issue a delay_span_bug ICE on the following code: ```rust pub fn a() -> impl Fn() -> u32 { || content::doesnt::matter() } ``` This wasn't picked up earlier because having `type Alias = impl Trait;` in the same module caused _all closures_ to be typechecked, even if they wouldn't normally. Additionally, if _any_ error was emitted, no delay_span_bug would be emitted. So as part of this commit all of the tests were separated out into different files.

Each of these needs to be in a separate file,
fix typo

because the `span_delayed_bug` ICE in rustdoc won't be triggered

if even a single other error was emitted.
However, conceptually they are all testing basically the same thing.
