Remove unused `check-stage2-T-arm-linux-androideabi-H-x86_64-unknown-linux-gnu` make rule
It's not used anywhere in CI, and it seems of questionable use. It was first added in 0e272de69f4a9c889e5f1a024a88b3e1f60cb6c5, which looks like it's just intended for CI, not as a user-facing feature.
Avoid going through the happy path in case of non-fn builtin calls
No functional change, just doing an early return. The removed comment is not applicable anymore, not every node needs type bindings in the error case. At best this would have been needed to avoid ICEs, but afaict this can't happen anymore today, as we do fallible checks.
rustdoc: simplify section anchor CSS
Since f50bf8636e3b0296db82e631fe95c84324a46ccc changed anchors to be always positioned absolute, specifying it on hover as well is redundant.
Bump `cfg-if` to `1.0` in rustc crates
When `packed_simd_2` and `getrandom` are updated to newer versions, we will no longer have a dependency on old `cfg_if` versions.
Fix an opaque type ICE
fixes#104551
The issue is that if you have
```rust
type T = impl Sized;
let (_a, _b): T = ..
```
we have only the type annotation `T`, but want to use that ascription for `_a` and `_b`, so what we generate is a type ascription plus a field projection saying `_a`'s type is `T::0`. Of course `T` has no fields. Of course we could also not generate type annotations for projections into opaque types at all, but that's more fragile, as we now have to make sure that 12bbdbdb44/compiler/rustc_mir_build/src/build/matches/mod.rs (L709) doesn't have any arm that introduces a user type annotation except for `PatKind::Binding`.
docs: add long error explanation for error E0472
Add long-form error docs for E0472: "inline assembly not supported on this target" and update UI tests.

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
Fixes https://github.com/rust-lang/rust/issues/84628.

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.
r? `@lcnr`
cc `@oli-obk` who had asked for this to be a lint first
Not sure if this needs to be an FCP, since it's a lint for now.
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
