6689d2df08 Rollup merge of #105955 - Nilstrieb:no-trivial-opt-wrappers-we-have-field-accesses-for-that, r=cjgillot 
Remove wrapper functions for some unstable options

They are trivial and just forward to the option. Like most other options, we can just access it directly.

Fix an outdated comment mentioning parameter that doesn't exist anymore

I'm not too familiar with the code in question, but from what I see I think the new comment makes sense.

r? `@cjgillot` (you touched these arguments lately https://github.com/rust-lang/rust/pull/91557/files#diff-ad0c15bbde97a607d4758ec7eaf88248be5d6b8ae084dfc84127f81e3f7a9bb4L1702, https://github.com/rust-lang/rust/pull/104048/files#diff-ad0c15bbde97a607d4758ec7eaf88248be5d6b8ae084dfc84127f81e3f7a9bb4L1682)

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.

fd5af8cc23 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.

3e58de240c 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?

Add a missing early return in drop tracking `handle_uninhabited_return`

This return is needed so we don't call `Ty::is_inhabited_from` from a type with ty/ct vars in it.

548d49c789 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.

Fixes #104396
