Refer to "Waker" rather than "RawWaker" in `drop` comment
In my view this is technically more correct as `Waker` actually implements `Drop` (which calls the `drop` method) whereas `RawWaker` does not.
str.lines() docstring: clarify that line endings are not returned
Previously, the str.lines() docstring stated that lines are split at line endings, but not whether those were returned or not. This new version of the docstring states this explicitly, avoiding the need of getting to doctests to get an answer to this FAQ.

Implement `From<bool>` for f32, f64
As is required for trait implementations, these are insta-stable. Given there is a release tomorrow and this needs FCP, I set 1.65 as the stable version.

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 0e272de69f, 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.
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.
