Rollup merge of #129860 - lqd:remove-duplicate-deps, r=alexcrichton
update `object` dependency to remove duplicate `wasmparser`

``@alexcrichton`` in #129762 you bumped a few wasm-related dependencies and tried to avoid duplicates.

If I understand correctly, `object` 0.36.4 wasn't yet released at the time, and therefore #129762 ended up duplicating `wasmparser`. Now that the release happened, we can remove the duplicate.

Rollup merge of #129800 - ChrisDenton:remove-dir-all2, r=Amanieu
Move the Windows remove_dir_all impl into a module and make it more race resistant

This attempts to make the Windows implementation of `remove_dir_all` easier to understand and work with by separating out different concerns into their own functions. The code is mostly the same as before just moved around. There are some changes to make it more robust against races (e.g. two calls to `remove_dir_all` running concurrently). The module level comment explains the issue.

Rollup merge of #129892 - oskgo:clarify-slice-from-raw, r=RalfJung
Clarify language around ptrs in slice::raw

More specifically we explicitly mention that the pointer should be non-null as a top level requirement. Nullptrs are always valid for zero sized operations, so just validity (and alignment) does not guarantee non-nullness as implied in the existing docs.

We also explicitly call out ZSTs as an additional example where perhaps unintuitively alignment and non-nullness still have to hold.

Finally we change `data` in the range functions to `start`, which seems like a typo to me.

Touches docs for #89792

compiler_fence documentation: emphasize synchronization, not reordering

Our `fence` docs have at some point been update to explain that they are about synchronization, not about "preventing reordering". This updates the `compiler_fence` docs n the same vein, mostly by referring to the `fence` docs.

The old docs make it sound like I can put a compiler_fence in the middle of a bunch of non-atomic operations and that would achieve any kind of guarantee. It does not, atomic operations are still required to do synchronization.

I also slightly tweaked the `fence` docs, to put the synchronization first and the "prevent reordering" second.

Rollup merge of #129829 - compiler-errors:decode-non-optional, r=lcnr
Make decoding non-optional `LazyArray` panic if not set

Tables may be [defined](9649706ead/compiler/rustc_metadata/src/rmeta/mod.rs (L377)) as `optional:` or `defaulted:`. If optional, if we try to read a value from a key that was never encoded, we should panic. This has high value in ensuring correctness over a defaulted table, so the tradeoff is worth considering, since it signals the compiler has a buggy encode impl, rather than just defaulting to a value.

HOWEVER, `optional:` arrays were side-stepping this. So this PR fixes that, and makes `optional:` tables of `LazyArray` act like `LazyValue`, and panic if it's not assigned a value during encoding.

During this PR, I found that `deduced_param_attrs` has buggy (?? i think??) implementation where it will refuse to encode cross-crate `deduced_param_attrs` unless we're codegening, we're optimizing the library, and incremental is disabled. This seems incredibly wrong, but I don't want to fix it in this PR.

bd53aa3bf7 Auto merge of #129317 - compiler-errors:expectation-subtyping, r=lcnr
Use equality when relating formal and expected type in arg checking

#129059 uncovered an interesting issue in argument checking. When we check arguments, we create three sets of types:
* Formals
* Expected
* Actuals

The **actuals** are the types of the argument expressions themselves. The **formals** are the types from the signature that we're checking. The **expected** types are the formal types, but passed through `expected_inputs_for_expected_outputs`:

a971212545/compiler/rustc_hir_typeck/src/fn_ctxt/_impl.rs (L691-L725)

This method attempts to constrain the formal inputs by relating the [expectation](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_hir_typeck/expectation/enum.Expectation.html) of the call expression and the formal output.

When we check an argument, we get the expression's actual type, and then we first attempt to coerce it to the expected type:

a971212545/compiler/rustc_hir_typeck/src/fn_ctxt/checks.rs (L280-L293)

Then we subtype the expected type and the formal type:

a971212545/compiler/rustc_hir_typeck/src/fn_ctxt/checks.rs (L299-L305)

However, since we are now recording the right coercion target (since #129059), we now end up recording the expected type to the typeck results, rather than the actual.

Since that expected type was [fudged](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_infer/infer/struct.InferCtxt.html#method.fudge_inference_if_ok), it has fresh variables. And since the expected type is only subtyped against the formal type, if that expected type has a bivariant parameter, it will likely remain unconstrained since `Covariant * Bivariant = Bivariant` according to [xform](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_middle/ty/enum.Variance.html#method.xform). This leads to an unconstrained type variable in writeback.

AFAICT, there's no reason for us to be using subtyping here, though. The expected output is already related to the expectation by subtyping:

a971212545/compiler/rustc_hir_typeck/src/fn_ctxt/_impl.rs (L713)

So the formals don't need "another" indirection of subtyping in the argument checking... So I've changed it to use equality here. We could alternatively fix this by requiring WF for all the expected types to constrain their bivariant parameters, but this seems a bit overkill.
