Rollup merge of #105949 - ChrisDenton:bump-cfg-if, r=Nilstrieb 
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.

Rollup merge of #105897 - oli-obk:tait_patterns, r=TaKO8Ki 
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`.

fb89ae4092 Remove unused check-stage2-T-arm-linux-androideabi-H-x86_64-unknown-linux-gnu 
It's not used anywhere in CI, and it seems of questionable use.
It was first added in 0e272de69f, which looks like it's just intended for CI, not as a user-facing feature.

a65ec44779 Add -Zno-jump-tables 
This flag mimics GCC/Clang's `-fno-jump-tables` [1][2], which makes
the codegen backend avoid generating jump tables when lowering switches.

In the case of LLVM, the `"no-jump-tables"="true"` function attribute is
added to every function.

The kernel currently needs it for x86 when enabling IBT [3], as well
as for Alpha (plus VDSO objects in MIPS/LoongArch).

[2] https://clang.llvm.org/docs/ClangCommandLineReference.html#cmdoption-clang-fjump-tables

d6da428f34 Auto merge of #105381 - uweigand:s390x-ffi-vaarg, r=nikic 
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.

Bump packed_simd_2 and getrandom v0.2 
Remove old versions of `cfg-if` by bumping `packed_simd_2` and `getrandom v0.2` versions

```console
> cargo update --package packed_simd_2 --package getrandom@0.2.0
    Updating crates.io index
    Removing cfg-if v0.1.10
    Updating getrandom v0.2.0 -> v0.2.8
    Updating packed_simd_2 v0.3.4 -> v0.3.8
```

`packed_simd_2` is only used as a dependency `bytecount`. The bigger jump is `getrandom@0.2.0`, but it's still semver compatible and there doesn't seem to be any worrying changes (see the [changelog](https://github.com/rust-random/getrandom/blob/master/CHANGELOG.md)). Note that this doesn't affect `getrandom@0.1.16`, which is already using the latest version of `cfg-if` (besides, there are already plans to remove that entirely).
