Rollup merge of #48221 - rkruppe:improve-ctypes-lint, r=estebank 
Overhaul improper_ctypes output

This snowballed into a rather big set of improvements to the diagnostics of the improper_ctypes lint. See commits for details, including effects of each change on the `compile-fail/improper-ctypes.rs` test (now a UI test), which is pretty gnarly and hopefully not representative of real code, but covers a lot of different error cases.

Fixes #42050

Rollup merge of #48157 - scottmcm:try-for-each, r=dtolnay 
Add Iterator::try_for_each

The fallible version of `for_each` aka the stateless version of `try_fold`.  Inspired by @cuviper's comment in https://github.com/rust-lang/rust/pull/45379#issuecomment-338370020 as a more direct and obvious solution than `.map(f).collect::<Result<(), _>>()`.

Like `for_each`, no need for an `r` version thanks to overrides in `Rev`.

Rollup merge of #48123 - nikomatsakis:issue-47244-expected-num-args, r=estebank 
detect wrong number of args when type-checking a closure

Instead of creating inference variables for those argument types, use
the trait error-reporting code to give a nicer error. This also
improves some other spans for existing tests.

Fixes #47244

2370b60529 update tests and reference files 
The type checker invokes the borrow checker for closures it finds, so
removing the NLL type checker affects ordering of errors somewhat.

063deba92e Auto merge of #47799 - topecongiro:fix-span-of-visibility, r=petrochenkov 
Fix span of visibility

This PR

1. adds a closing parenthesis to the span of `Visibility::Crate` (e.g. `pub(crate)`). The current span only covers `pub(crate`.
2. adds a `span` field to `Visibility::Restricted`. This span covers the entire visibility expression (e.g. `pub (in self)`). Currently all we can have is a span for `Path`.

This PR is motivated by the bug found in rustfmt (https://github.com/rust-lang-nursery/rustfmt/issues/2398).

The first change is a strict improvement IMHO. The second change may not be desirable, as it adds a field which is currently not used by the compiler.

rustc_mir: handle all aggregate kinds in, and always run, the deaggregator.

This helps with removing`Rvalue::Aggregate` from the MIR, and with enabling more optimizations.

8b2037c6fe Introduce UnpackedKind 
This adds an `UnpackedKind` type as a typesafe counterpart to `Kind`. This should make future changes to kinds (such as const generics!) more resilient, as the type-checker should catch more potential issues.

311fbc9265 [docs] Minor wording changes to drain_filter docs 
The docs currently say, "If the closure returns false, it will try
again, and call the closure on the next element."  But this happens
regardless of whether the closure returns true or false.

This updates the book repository, but mostly to include
