To more easily allow rustfmt to format the ``asm!`` macro as specified in
rust-dev-tools/fmt-rfcs#152 certain fields are made public.

Eliminate "boxed" wording in `std::error::Error` documentation
In commit 29403ee, documentation for the methods on `std::any::Any` was
modified so that they referred to the concrete value behind the trait
object as the "inner" value. This is a more accurate wording than
"boxed": while putting trait objects inside boxes is arguably the most
common use, they can also be placed behind other pointer types like
`&mut` or `std::sync::Arc`.
This commit does the same documentation changes for `std::error::Error`.
Add note about upstream commit musl-patch-configure.diff is derived from
The patch landed in upstream over the weekend so I'm adding a note so we can more easily track when our patch file can be removed.
Improve documentation for File::options to give a more likely example
`File::options().read(true).open(...)` is equivalent to just
`File::open`. Change the example to set the `append` flag instead, and
then change the filename to something more likely to be written in
append mode.
rustdoc: Display "private fields" instead of "fields omitted"
Also:
* Always use `/* */` block comments
* Use the same message everywhere, rather than sometimes prefixing
with "some"
When I first read rustdoc docs, I was confused why the fields were being
omitted. It was only later that I realized it was because they were
private. It's also always bothered me that rustdoc sometimes uses `//`
and sometimes uses `/*` comments for these messages, so this change
makes them all use `/*`.
Technically, I think fields can be omitted if they are public but
`doc(hidden)` too, but `doc(hidden)` is analogous to privacy. It's
really just used to emulate "doc privacy" when -- because of technical
limitations -- an item has to be public. So I think it's fine to include
this under the category of "private fields".

Error when selected impl is not const in constck
Catches bad things when checking a `default_method_body_is_const` body, such as:
```rust
self.map(/* .. */).is_sorted();
```
When `Map` does not yet have a `const` `impl` for `Iterator`.

Store a `Symbol` instead of an `Ident` in `VariantDef`/`FieldDef`
The field is also renamed from `ident` to `name`. In most cases,
we don't actually need the `Span`. A new `ident` method is added
to `VariantDef` and `FieldDef`, which constructs the full `Ident`
using `tcx.def_ident_span()`. This method is used in the cases
where we actually need an `Ident`.
This makes incremental compilation properly track changes
to the `Span`, without all of the invalidations caused by storing
a `Span` directly via an `Ident`.
Actually instantiate the opaque type when checking bounds
Before this change, `instantiate_opaque_types` was a no-op, because it only works relative to the defined opaque type inference anchor. If it is a no-op, the for loop will not actually have anything to iterate over, and thus nothing is checked at all.

Replace usages of vec![].into_iter with [].into_iter
`[].into_iter` is idiomatic over `vec![].into_iter` because its simpler and faster (unless the vec is optimized away in which case it would be the same)
So we should change all the implementation, documentation and tests to use it.
I skipped:
* `src/tools` - Those are copied in from upstream
* `src/test/ui` - Hard to tell if `vec![].into_iter` was used intentionally or not here and not much benefit to changing it.
* any case where `vec![].into_iter` was used because we specifically needed a `Vec::IntoIter<T>`
* any case where it looked like we were intentionally using `vec![].into_iter` to test it.
rustdoc: Remove the intra-doc links side channel
The side channel made the code much more complex and harder to
understand. It was added as a temporary workaround in
0c99d806ea, but it's no longer necessary.
The addition of `UrlFragment` in #92088 was the key to getting rid of
the side channel. The semantic information (rather than the strings that
used to be used for fragments) that is now captured by `UrlFragment` is
enough to obviate the side channel. An additional change had to be made
to `UrlFragment` in this PR to make this possible: it now records
`DefId`s rather than item names.
This PR also consolidates the checks for anchor conflicts into one place.

Normalize generator-local types with unevaluated constants
Normalize generator-interior types in addition to (i.e. instead of just) erasing regions, since sometimes we collect types with unevaluated const exprs.
Fixes#84737Fixes#88171Fixes#92091Fixes#92634
Probably also fixes#73114, but that one has no code I could test. It looks like it's the same issue, though.
Normalize struct tail type when checking Pointee trait
Let's go ahead and implement the FIXMEs by properly normalizing the struct-tail type when satisfying a Pointee obligation. This should fix the ICE when we try to calculate a layout depending on `<Ty as Pointee>::Metadata` later.
Fixes#92128Fixes#92577
Additionally, mark the obligation as ambiguous if there are any infer types in that struct-tail type. This has the effect of causing `<_ as Pointee>::Metadata` to be properly replaced with an infer variable ([here](https://github.com/rust-lang/rust/blob/master/compiler/rustc_trait_selection/src/traits/project.rs#L813)) and registered as an obligation... this turns out to be very important in unifying function parameters with formals that are assoc types.
Fixes#91446
Ensure that `Fingerprint` caching respects hashing configuration
Fixes#92266
In some `HashStable` impls, we use a cache to avoid re-computing
the same `Fingerprint` from the same structure (e.g. an `AdtDef`).
However, the `StableHashingContext` used can be configured to
perform hashing in different ways (e.g. skipping `Span`s). This
configuration information is not included in the cache key,
which will cause an incorrect `Fingerprint` to be used if
we hash the same structure with different `StableHashingContext`
settings.
To fix this, the configuration settings of `StableHashingContext`
are split out into a separate `HashingControls` struct. This
struct is used as part of the cache key, ensuring that our caches
always produce the correct result for the given settings.
With this in place, we now turn off `Span` hashing during the
entire process of computing the hash included in legacy symbols.
This current has no effect, but will matter when a future PR
starts hashing more `Span`s that we currently skip.
