Rollup merge of #106066 - JohnTitor:rm-bindings-after-at-fixme, r=compiler-errors 
Always suggest as `MachineApplicable` in `recover_intersection_pat`

This resolves one FIXME in `recover_intersection_pat` by always applying `MachineApplicable` when suggesting, as `bindings_after_at` is now stable.
This also separates a test to apply `// run-rustfix`.

731e0bf721 Auto merge of #103828 - cassaundra:fix-format-args-span2, r=cjgillot 
Fix incorrect span when using byte-escaped rbrace

Fix #103826, a format args span issue introduced in #102214.

The current solution for tracking skipped characters made it so that certain situations were ambiguous enough that the original span couldn't be worked out later. This PR improves on the original solution by keeping track of groups of skipped characters using a map, and fixes the previous bug. See an example of this ambiguity in the [previous PR's discussion](https://github.com/rust-lang/rust/pull/102214#issuecomment-1258711015).

f206533fd4 Auto merge of #105605 - inquisitivecrystal:attr-validation, r=cjgillot 
Don't perform invalid checks in `codegen_attrs`

The attributes `#[track_caller]` and `#[cmse_nonsecure_entry]` are only valid on functions. When validating one of these attributes, codegen_attrs previously called `fn_sig`, [which can only be used on functions](https://github.com/rust-lang/rust/pull/105201), on the item the attribute was attached to, assuming that the item was a function without checking. This led to [ICEs in situations where the attribute was incorrectly used on non-functions](https://github.com/rust-lang/rust/issues/105594).

With this change, we skip calling `fn_sig` if the item the attribute is attached to must be a function but isn't, because `check_attr` will reject such cases without codegen_attrs's intervention.

As a side note, some of the attributes in codegen_attrs are only valid on functions, but that property isn't actually checked. I'm planning to fix that in a follow up PR since it's a behavior change that will need to be validated rather than an obvious bugfix. Thankfully, all the attributes like that I've found so far are unstable.

Fixes #105594.

8dfb339541 Auto merge of #105997 - RalfJung:immediate-abort, r=eholk 
abort immediately on bad mem::zeroed/uninit

Now that we have non-unwinding panics, let's use them for these assertions. This re-establishes the property that `mem::uninitialized` and `mem::zeroed` will never unwind -- the earlier approach of causing panics here sometimes led to hard-to-debug segfaults when the surrounding code was not able to cope with the unexpected unwinding.

Cc `@bjorn3` I did not touch cranelift but I assume it needs a similar patch. However it has a `codegen_panic` abstraction that I did not want to touch since I didn't know how else it is used.

Rollup merge of #105661 - lcnr:evaluate-new, r=compiler-errors 
implement the skeleton of the updated trait solver

cc ```@rust-lang/initiative-trait-system-refactor```

This is mostly following the architecture discussed in the types team meetup.

After discussing the desired changes for the trait solver, we encountered cyclic dependencies between them. Most notably between changing evaluate to be canonical and returning inference constraints. We cannot canonicalize evaluate without returning inference constraints due to coinductive cycles. However, caching inference constraints also relies on canonicalization. Implementing both of these changes at once in-place is not feasible.

This somewhat closely mirrors the current `evaluate` implementation with the following notable differences:
- it moves `project` into the core solver, allowing us to correctly deal with coinductive projections (will be required for implied bounds, perfect derive)
- it changes trait solver overflow to be non-fatal (required to backcompat breakage from changes to the iteration order of nested goals, deferred projection equality, generally very useful)
- it returns inference constraints and canonicalizes inputs and outputs (required for a lot things, most notably merging fulfill and evaluate, and deferred projection equality)
- it is implemented to work with lazy normalization

A lot of things aren't yet implemented, but the remaining FIXMEs should all be fairly self-contained and parallelizable. If the architecture looks correct and is what we want here, I would like to quickly merge this and then split the work.

Rollup merge of #106051 - jyn514:cranelift-std, r=bjorn3 
Allow building std with cranelift

- Don't pass llvm-specific args when using cranelift
- Don't use `asm` in compiler_builtins when using cranelift

Rollup merge of #105978 - jyn514:unused_proc_macro_decl, r=tmiasko 
Mark `proc_macro_decls_static` as always used

This would have avoided a bug in https://github.com/rust-lang/rust/pull/104860.

In practice this shouldn't matter since nothing uses the query other than the `dead_code` lint, but this isn't documented as an internal-only query so it seems nice for it to be accurate. I think for `dead_code` it doesn't matter because the relevant code is generated by `rustc_builtin_macros` and isn't linted.

I think `@tmiasko` or `@bjorn3` would be a good reviewer?
