0e07c4281c Auto merge of #54762 - RalfJung:miri-validate, r=oli-obk
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).

Fixes https://github.com/rust-lang/rust/issues/53826

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.
