Implement va_list and va_arg for s390x FFI

Following the s390x ELF ABI and based on the clang implementation, provide appropriate definitions of va_list in library/core/src/ffi/mod.rs and va_arg handling in compiler/rustc_codegen_llvm/src/va_arg.rs.

Fixes the following test cases on s390x:
src/test/run-make-fulldeps/c-link-to-rust-va-list-fn src/test/ui/abi/variadic-ffi.rs

eb9e5e711d Auto merge of #105880 - Nilstrieb:make-newtypes-less-not-rust, r=oli-obk
Improve syntax of `newtype_index`

This makes it more like proper Rust and also makes the implementation a lot simpler.

Mostly just turns weird flags in the body into proper attributes.

It should probably also be converted to an attribute macro instead of function-like, but that can be done in a future PR.

Add `IMPLIED_BOUNDS_ENTAILMENT` lint

Implements a lint (#105572) version of the hard-error introduced in #105483. Context is in that PR.

Not sure if this needs to be an FCP, since it's a lint for now.

696563efc5 Auto merge of #105905 - lqd:revert-103880, r=jackh726
Revert #103880 "Use non-ascribed type as field's type in mir"

This PR prepares a revert for #103880 to fix #105809, #105881, #105886 and others (like the duplicates of the first one), in case an actual fix can't get done today.

I've also added the MCVE from #105809. There is no MCVE for the #105881 and #105886 ICEs yet however, so there are no tests for them here, although we'll need one before relanding the original changes.

Were this PR to land, it would also reopen #96514 as it was fixed by the original PR.

Opening as draft to allow time for a possible fix.

Revert "Replace usage of `ResumeTy` in async lowering with `Context`"

Reverts rust-lang/rust#105250
Fixes: #105501

Following instructions from [forge](https://forge.rust-lang.org/compiler/reviews.html#reverts).

This change introduced a breaking change that is not actionable nor relevant, and is blocking updates to our toolchain. Along with other comments on the CL marking issues that are fixed by reverts, reverting is best until these issues can be resolved

Rollup merge of #105839 - LegionMammal978:mut-upvar-not-send, r=lcnr
Suggest a `T: Send` bound for `&mut T` upvars in `Send` generators

Right now, we suggest a `T: Sync` bound for both `&T` and `&mut T` upvars. A user on URLO [found this confusing](https://users.rust-lang.org/t/error-complains-about-missing-sync-but-send-is-whats-missing/86021), so I wrote this quick fix to look at the mutability before making the suggestion.

Rollup merge of #105842 - compiler-errors:arg-name-sugg, r=petrochenkov
print argument name in arg mismatch if possible

A bit more contextual than just `/* value */`, at least when the argument is named something related to its context.

The UI test cases are... not super convincing, but also they're minimized tests.

2b094b1ede Auto merge of #105446 - erikdesjardins:vt-size, r=nikic
Add 0..=isize::MAX range metadata to size loads from vtables

This is the (much belated) size counterpart to #91569.

Inspired by https://rust-lang.zulipchat.com/#narrow/stream/187780-t-compiler.2Fwg-llvm/topic/Range.20metadata.20for.20.60size_of_val.60.20and.20other.20isize.3A.3AMAX.20limits. This could help optimize layout computations based on the size of a dyn trait. Though, admittedly, adding this to vtables wouldn't be as beneficial as adding it to slice len, which is used much more often.

Miri detects this UB already: b7cc99142a/compiler/rustc_const_eval/src/interpret/traits.rs (L119-L121)
(In fact Miri goes further, [assuming a 48-bit address space on 64-bit platforms](9db224fc90/compiler/rustc_abi/src/lib.rs (L312-L331)), but I don't think we can assume that in an optimization.)

8bfd6450c7 A few small cleanups for newtype_index
Remove the `..` from the body, only a few invocations used it and it's
inconsistent with rust syntax.

Use `;` instead of `,` between consts. As the Rust syntax gods inteded.
