Addresses Issue 98466 by emitting a warning if a named argument
is used like a position argument (i.e. the name is not used in
the string to be formatted).

Pull Derefer before ElaborateDrops
_Follow up work to #97025#96549#96116#95887 #95649_
This moves `Derefer` before `ElaborateDrops` and creates a new `Rvalue` called `VirtualRef` that allows us to bypass many constraints for `DerefTemp`.

Use `LazyLock` for `lint_message_convention` regexes
They were being recompiled for `Message::new` call, for me this shaves 7s off the time it takes to run the test. Also removes a redundant exception from the list and joins the various `message...` exceptions into one
changelog: none
Refactor: remove an unnecessary `span_to_snippet`
`span_suggestion_hidden` does not show the suggested code and the suggestion is used just for rustfix, so `span_to_snippet` is unnecessary here.
Keep unstable target features for asm feature checking
Inline assembly uses the target features to determine which registers
are available on the current target. However it needs to be able to
access unstable target features for this.
Fixes#99071
diagnostics: error messages when struct literals fail to parse
If an expression is supplied where a field is expected, the parser can become convinced that it's a shorthand field syntax when it's not.
This PR addresses it by explicitly recording the permitted `:` token immediately after the identifier, and also adds a suggestion to insert the name of the field if it looks like a complex expression.
Fixes#98917
Lower let-else in MIR
This MR will switch to lower let-else statements in MIR building instead.
To lower let-else in MIR, we build a mini-switch two branches. One branch leads to the matching case, and the other leads to the `else` block. This arrangement will allow temporary lifetime analysis running as-is so that the temporaries are properly extended according to the same rule applied to regular `let` statements.

fix [`manual_flatten`] help texts order
fixes #8948
Whenever suggestion for this lint does not fit in one line,
legacy solution has some unexpected/unhandled behavior:
lint will then generate two help messages which seem to be shown in the wrong order.
The second help message in that case will contain the suggestion.
The first help message always refers to a suggestion message,
and **it should adapt** depending on the location of the suggestion:
- inline suggestion within the error/warning message
- suggestion separated into a second help text
This is my first contribution here, so I hope I didn't miss anything for creating this PR.

Mention rust-analyzer maintainers when `proc_macro` bridge is changed
rust-analyzer vendors a modified copy of the `proc_macro` crate in order to expand procedural macros built by Cargo. Since the ABI used by proc macros can change, we need to follow along with those changes. Getting notified when the proc macro bridge changes should make that easier, since that's what defines the ABI.
