f65d3b5491 switch validation of scalars to be type-driven 
This does not actually regress anything.  It would regress NonNull, but we
didn't handle that correctly previously either.

Improve message for closure returning a closure. 
Now when a `FnMut` closure is returning a closure that contains a
reference to a captured variable, we provide an error that makes it more
clear what is happening.

Improve errors for FnMut closures. 
This commit improves the errors for `FnMut` closures where a reference
to a captured variable is escaping.

[NLL]  Improve closure region bound errors

Previously, we would report free region errors that originate from closure with the span of the closure and a "closure body requires ..." message. This is now updated to use a reason and span from inside the closure.

ac33b2e578 Run debuginfo tests against rust-enabled lldb, when possible 
If the rust-enabled lldb was built, then use it when running the
debuginfo tests.  Updating the lldb submodule was necessary as this
needed a way to differentiate the rust-enabled lldb, so I added a line
to the --version output.

This adds compiletest commands to differentiate between the
rust-enabled and non-rust-enabled lldb, as is already done for gdb.  A
new "rust-lldb" header directive is also added, but not used in this
patch; I plan to use it in #54004.

This updates all the tests.

efd7a31150 in which rightward drift is opposed 
Thanks to reviewers Tyler Mandry (for pointing out that this is
ridiculous and we need a helper function), Niko Matsakis (for pointing
out that the span-calculation code only has a couple free variables),
and Esteban Küber (for pointing out `get_generics`).

aefe9b099a Auto merge of #54609 - kzys:404-search, r=GuillaumeGomez 
Add the library search box on the 404 page

It actually has a link to search already, but it would be better to
have the search "box" as like index.md to be consistent.

<style> can be shared with index.md, but these pages currently
use https://doc.rust-lang.org/rust.css directly.

Fixes #14572.

Update logic to search for casts. 
This commit updates the captured trait object search logic to look for

Identify borrows captured by trait objects. 
This commit enhances `LaterUseKind` detection to identify when a borrow
