Stop using CRATE_DEF_INDEX outside of metadata encoding.

`CRATE_DEF_ID` and `CrateNum::as_def_id` are almost always what we want.  We should not manipulate raw `DefIndex` outside of metadata encoding.

cbdf17c884 Auto merge of #8707 - OneSignal:await-invalid-types, r=llogiq 
Add `await_holding_invalid_type` lint

changelog: [`await_holding_invalid_type`]

This lint allows users to create a denylist of types which are not allowed to be
held across await points. This is essentially a re-implementation of the
language-level [`must_not_suspend`
lint](https://github.com/rust-lang/rust/issues/83310). That lint has a lot of
work still to be done before it will reach Rust stable, and in the meantime
there are a lot of types which can trip up developers if they are used
improperly.

I originally implemented this specifically for `tracing::span::Entered`, until I discovered #8434 and read the commentary on that PR. Given this implementation is fully user configurable, doesn't tie clippy to any one particular crate, and introduces no additional dependencies, it seems more appropriate.

95de4dcb5e Auto merge of #8701 - xFrednet:0000-clippy-print-hir-attr, r=flip1995 
Rework `#[clippy::dump]` attribute for debugging

Hey `@rust-lang/clippy,` this adds a new `#[clippy::print_hir]` attribute that prints the node to the console using `{:#?}`. Personally, I use print debugging quite a lot while working on Clippy, and this is a simple shortcut that also works in the playground (Once this has been synced). The question is now, if we want to have this attribute. Are there any concerns? I think it's similar to our `#[clippy::author]` attribute.

I haven't added a test, as the `.stdout` file would require updates with every HIR change inside rustc. Here are some examples, for the current implementation

Report undeclared lifetimes during late resolution.

First step in https://github.com/rust-lang/rust/pull/91557

We reuse the rib design of the current resolution framework. Specific `LifetimeRib` and `LifetimeRibKind` types are introduced. The most important variant is `LifetimeRibKind::Generics`, which happens each time we encounter something which may introduce generic lifetime parameters. It can be an item or a `for<...>` binder. The `LifetimeBinderKind` specifies how this rib behaves with respect to in-band lifetimes.

- use tcx.hir_crate_items to introduce a tcx.hir().par_items(impl Fn(hir::ItemId)) to traverse all items in parallel;

5cf2920ef3 Auto merge of #94468 - Amanieu:global_asm_sym, r=nagisa 
Implement sym operands for global_asm!

Tracking issue: #93333

This PR is pretty much a complete rewrite of `sym` operand support for inline assembly so that the same implementation can be shared by `asm!` and `global_asm!`. The main changes are:
- At the AST level, `sym` is represented as a special `InlineAsmSym` AST node containing a path instead of an `Expr`.
- At the HIR level, `sym` is split into `SymStatic` and `SymFn` depending on whether the path resolves to a static during AST lowering (defaults to `SynFn` if `get_early_res` fails).
  - `SymFn` is just an `AnonConst`. It runs through typeck and we just collect the resulting type at the end. An error is emitted if the type is not a `FnDef`.
  - `SymStatic` directly holds a path and the `DefId` of the `static` that it is pointing to.
- The representation at the MIR level is mostly unchanged. There is a minor change to THIR where `SymFn` is a constant instead of an expression.
- At the codegen level we need to apply the target's symbol mangling to the result of `tcx.symbol_name()` depending on the target. This is done by calling the LLVM name mangler, which handles all of the details.
  - On Mach-O, all symbols have a leading underscore.
  - On x86 Windows, different mangling is used for cdecl, stdcall, fastcall and vectorcall.
  - No mangling is needed on other platforms.

4844325faf Add await_holding_invalid_type lint 
changelog: [`await_holding_invalid_type`]

This lint allows users to create a denylist of types which are not allowed to be
held across await points. This is essentially a re-implementation of the
language-level [`must_not_suspend`
lint](https://github.com/rust-lang/rust/issues/83310). That lint has a lot of
work still to be done before it will reach Rust stable, and in the meantime
there are a lot of types which can trip up developers if they are used
improperly.

Spellcheck

I'm brand new to this so any feedback will be helpful. I set the project up locally and ran a spellcheck on it. The code changes should only be spelling corrections. I ran the build and tests and they came back successful locally.

changelog: Various spelling corrections in comments and code.

Check var scope if it exist

Fixes #92893.

Added helper function to check the scope of a variable, if it doesn't have a scope call delay_span_bug, which avoids us trying to get a block/scope that doesn't exist.

Had to increase `ROOT_ENTRY_LIMIT` was getting tidy error

Pinging `@dtolnay.` I think this is enough to fix the issue. Do you have a good list crates to test this on?
