Fix drop-tracking ICE when a struct containing a field with a significant drop is used across an await
Previously, drop-tracking would incorrectly assume the struct would be dropped immediately, which was not true.
Fixes#98476. Also fixes https://github.com/rust-lang/rust/issues/98477, I think because the parent HIR node for type variables is the whole function instead of the expression where the variable is used.

allow unions with mutable references and tuples of allowed types
We currently allow shared references in unions, but not mutable references. That seems somewhat inconsistent. So let's allow all references, and while we are at it, let's make sure the set of allowed types is closed under tuples.
This will need T-lang FCP (at least).
Then remove the `tagged_unions` feature, since we do not plan to stabilize any more of it.

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`.

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.

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.

Build the Clippy book as part of x.py doc
r? ``@ehuss`` since you said you would be interested in helping moving this forward.
cc ``@jyn514`` as part of the bootstrap team.
rustdoc-json-types: Clean up derives.
Closes#96189
Everything is `Clone, Debug, PartialEq, Eq, Hash, Serialize, Deserialize` except `Crate` and `Item` which arn't `Hash`, as they have `HashMap`'s. See linked issue for reasoning.

Remove most box syntax from librustdoc
This is the second attempt after the librustdoc specific changes have been reverted from #87781 in #89134, due to a minor, but exant regression caused by the changes. ~~There have been some changes to librustdoc in the past and maybe thanks to them there is no regression any more. If there is still a regression, one can investigate further and maybe find ways to fix the regressions. Thus, i request a perf run.~~ Edit: turns out there is still a regression, but it's caused only by a subset of the changes. So I've changed this PR to only contains the changes that don't cause any performance regressions, keeping the regression causing changes for a later PR.
Configure nightly branch name in `stage0.json`
The beta version number detection code relies on git to know how many merge commits were made since we branched off, and in doing so hardcodes `master` as the default branch name. This works for rust-lang/rust, but is problematic for forks that use a different default branch name (in Ferrocene we use `main` instead).
This PR changes the code to instead load the default branch name from `src/stage0.json`. `bump-stage0` has also been updated to remove the need to update it every time a new field is added to `stage0.json`.
interpret: refactor projection handling code
Moves our projection handling code into a common file, and avoids the use of a
general mplace-based fallback function by have more specialized implementations.
mplace_index (and the other slice-related functions) could be more efficient by
copy-pasting the body of operand_index. Or we could do some trait magic to share
the code between them. But for now this is probably fine.
This is the common part of https://github.com/rust-lang/rust/pull/99013 and https://github.com/rust-lang/rust/pull/99097. I am seeing some strange perf results so this probably should be its own change so we know which diff caused which perf changes...
