treat illumos like solaris in failing ui tests which need it
Just adding the right cfg target for tests which fail because they don't know illumos is a thing.

Make `select_*` methods return `Vec` for `TraitEngine`
This reduces some complexity as an empty vec means no errors and non-empty vec means errors occurred.
Don't abort compilation after giving a lint error
The only reason to use `abort_if_errors` is when the program is so broken that either:
1. later passes get confused and ICE
2. any diagnostics from later passes would be noise
This is never the case for lints, because the compiler has to be able to deal with `allow`-ed lints.
So it can continue to lint and compile even if there are lint errors.
Closes https://github.com/rust-lang/rust/issues/82761. This is a WIP because I have a feeling it will exit with 0 even if there were lint errors; I don't have a computer that can build rustc locally at the moment.
Don't destructure args tuple in format_args!
This allows Clippy to parse the HIR more simply since `arg0` is changed to `_args.0`. (cc rust-lang/rust-clippy#7843). From rustc's perspective, I think this is something between a lateral move and a tiny improvement since there are fewer bindings.

Merge `DocContext.{ty,lt,ct}_substs` into one map
It should be impossible to have more than one entry with a particular
key across the three maps, so they should be one map. In addition to
making it impossible for multiple entries to exist, this should improve
memory usage since now only one map is allocated on the stack and heap.

Fix bug with `#[doc]` string single-character last lines
Fixes#90618.
This is because `.iter().all(|c| c == '*')` returns `true` if there is no character checked. And in case the last line has only one character, it simply returns `true`, making the last line behind removed.
rustdoc: Cleanup `clean::Impl` and other parts of `clean`
This PR cleans up and reduces the size of `clean::Impl`, makes some other small performance improvements, and removes some Clean impls that are either unnecessary or potentially confusing.
r? `@jyn514`
Rustdoc is special as usual and doesn't go through RunCompiler, so it
needs its own explicit checks. The rest of the tools go through
RunCompiler, so they should be fine.

Improve error when an .rlib can't be parsed
This usually describes either an error in the compiler itself or some
sort of IO error. Either way, we should report it to the user rather
than just saying "crate not found".
This only gives an error if the crate couldn't be loaded at all - if the
compiler finds another .rlib or .rmeta file which was valid, it will
continue to compile the crate.
Example output:
```
error[E0785]: found invalid metadata files for crate `foo`
--> bar.rs:3:24
|
3 | println!("{}", foo::FOO_11_49[0]);
| ^^^
|
= warning: failed to parse rlib '/home/joshua/test-rustdoc/libfoo.rlib': Invalid archive extended name offset
```
cc `@ehuss`
This change has two advantages:
1. It makes the possible states clearer, and it makes it impossible to
construct invalid states, such as a blanket impl that is also an auto
trait impl.
2. It shrinks the size of `Impl` a bit, since now there is only one
field, rather than two.

TraitKind -> Trait
TyAliasKind -> TyAlias
ImplKind -> Impl
FnKind -> Fn
All `*Kind`s in AST are supposed to be enums.
Tuple structs are converted to braced structs for the types above, and fields are reordered in syntactic order.
Also, mutable AST visitor now correctly visit spans in defaultness, unsafety, impl polarity and constness.

Add features gates for experimental asm features
This PR splits off parts of `asm!` into separate features because they are not ready for stabilization.
Specifically this adds:
- `asm_const` for `const` operands.
- `asm_sym` for `sym` operands.
- `asm_experimental_arch` for architectures other than x86, x86_64, arm, aarch64 and riscv.

type error go brrrrrrrr
Fixes#90444
when we relate something like:
`fn(fn((), (), u32))` with `fn(fn((), (), ()))`
we relate the inner fn ptrs:
`fn((), (), u32)` with `fn((), (), ())`
yielding a `TypeError::ArgumentSorts(_, 2)` which we then use as the `TypeError` for the `fn(fn(..))` which later causes the ICE as the `2` does not correspond to any input or output types in `fn(_)`

Suggest dereference of `Box` when inner type is expected
For example:
enum Ty {
Unit,
List(Box<Ty>),
}
fn foo(x: Ty) -> Ty {
match x {
Ty::Unit => Ty::Unit,
Ty::List(elem) => foo(elem),
}
}
Before, the only suggestion was to rewrap `inner` with `Ty::Wrapper`,
which is unhelpful and confusing:
error[E0308]: mismatched types
--> src/test/ui/suggestions/boxed-variant-field.rs:9:31
|
9 | Ty::List(elem) => foo(elem),
| ^^^^
| |
| expected enum `Ty`, found struct `Box`
| help: try using a variant of the expected enum: `Ty::List(elem)`
|
= note: expected enum `Ty`
found struct `Box<Ty>`
Now, rustc will first suggest dereferencing the `Box`, which is most
likely what the user intended:
error[E0308]: mismatched types
--> src/test/ui/suggestions/boxed-variant-field.rs:9:31
|
9 | Ty::List(elem) => foo(elem),
| ^^^^ expected enum `Ty`, found struct `Box`
|
= note: expected enum `Ty`
found struct `Box<Ty>`
help: try dereferencing the `Box`
|
9 | Ty::List(elem) => foo(*elem),
| +
help: try using a variant of the expected enum
|
9 | Ty::List(elem) => foo(Ty::List(elem)),

Apply adjustments for field expression even if inaccessible
The adjustments are used later by ExprUseVisitor to build Place projections and without adjustments it can produce invalid result.
