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 #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?

Rollup merge of #105847 - compiler-errors:issue-104396, r=oli-obk 
Ensure param-env is const before calling `eval_to_valtree`

Other queries call `ParamEnv::with_const` *inside* of the query itself (e.g. `const_eval_global_id_for_typeck`), so this could alternatively be moved into the provider of `eval_to_valtree` instead. I don't have a particularly strong opinion, though *theoretically* caching is better if we make the query keys more constrained.

I'm not exactly sure how this is an effect of the `-Zmir-opt-level=3` flag. Maybe something about the inliner causes us to inline an unevaluated const into a body where it can be evaluated, but where it has not yet been normalized.

This seems likely, since we're inlining `from_fn_1::<{ N / 2 }, _>` in `from_fn_2`, which means that we will need to evaluate that constant during the const prop pass after inlining.

164e22109b 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.

Rollup merge of #104741 - bryangarza:bug-104588-async-track-caller, r=compiler-errors 
Switch `#[track_caller]` back to a no-op unless feature gate is enabled

This patch fixes a regression, in which `#[track_caller]`, which was previously a no-op, was changed to actually turn on the behavior. This should instead only happen behind the `closure_track_caller` feature gate.

Also, add a warning for the user to understand how their code will compile depending on the feature gate being turned on or not.

Correct branch-protection ModFlagBehavior for Aarch64 on LLVM-15

When building with Fat LTO and BTI enabled on aarch64, the BTI is set to `Module::Min` for alloc shim but is set to `Module::Error` for the crate. This was fine when we were using LLVM-14 but LLVM-15 changes it's behaviour to support for compiling with different `mbranch-protection` flags.

Rollup merge of #105837 - compiler-errors:issue-105728, r=estebank 
Don't ICE in `check_must_not_suspend_ty` for mismatched tuple arity

These expressions are just used for their spans, so make it best-effort here.

Rollup merge of #106008 - uweigand:s390x-lintgroup-order, r=Nilstrieb 
Sort lint_groups in no_lint_suggestion

The no_lint_suggestion routine passes a vector of lint group names to find_best_match_for_name.  That routine depends on the sort order of its input vector, which matters in case multiple inputs are at the same Levenshtein distance to the target name.

However, no_lint_suggestion currently just passes lint_groups.keys() as input vector - this is sorted in hash value order, which is not guaranteed to be stable, and in fact differs between big- and little-endian host platforms, causing test failures on s390x.

To fix this, always sort the lint groups before using their names as input to find_best_match_for_name.  In doing so, prefer non- deprecated lint group names over deprecated ones, and then use alphabetical order.

Rollup merge of #105602 - RalfJung:read-convenience, r=oli-obk 
interpret: add read_machine_[ui]size convenience methods

We have `read_pointer`, so it felt inconsistent to not also have these.
