Currently lldb tests are run only on macOS, and gdb tests are only run
elsewhere. This patch changes this to run tests depending on what is
available.
One test is changed, as it was previously marked as failing on macOS,
whereas really it is a generic failure with lldb.
Closes#54721
NLL is missing struct field suggestion
Part of #52663.
This commit adds suggestions to change the definitions of fields in
struct definitions from immutable references to mutable references.

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.
Fix range literals borrowing suggestions
Fixes#54505. The compiler issued incorrect range borrowing suggestions (missing `()` around borrows of range literals). This was not correct syntax (see the issue for an example).
With changes in this PR, this is fixed for all types of `Range` literals.
Thanks again to @varkor and @estebank for their invaluable help and guidance.

Prepare miri engine for enforcing validity invariant during execution
In particular, make recursive checking of references optional, and add a `const_mode` parameter that says whether `usize` is allowed to contain a pointer. Also refactor validation a bit to be type-driven at the "leafs" (primitive types), and separately validate scalar layout to catch `NonNull` violations (which it did not properly validate before).

[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.
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.
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`).
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.
Fix dead code lint for functions using impl Trait
Fixes https://github.com/rust-lang/rust/issues/54754
This is a minimal fix that doesn't add any new queries or touches unnecessary code. Please nominate for beta backport if wanted.
