Remove `{Early,Late}LintPassObjects`.
`EarlyContextAndPass` wraps a single early lint pass. We aggregate multiple passes into that single pass by using `EarlyLintPassObjects`.
This commit removes `EarlyLintPassObjects` by changing `EarlyContextAndPass` into `EarlyContextAndPasses`. I.e. it just removes a level of indirection. This makes the code simpler and slightly faster.
The commit does likewise for late lints.

This adds a new variant `ImplTraitContext::FeatureGated`, so we can
generalize the help for `return_position_impl_trait_in_trait` to also
work for `impl_trait_in_fn_trait_return`.
-export-dynamic was a temporary hack added in the early days of the Rust
wasm32 target when Rust didn't have a way to specify wasm exports in the
source code. This flag causes all global symbols, and some compiler-internal
symbols, to be exported, which is often more than needed.
Rust now does have a way to specify exports in the source code:
`#[export_name = "..."]`.
So as the original comment suggests, -export-dynamic can now be removed,
allowing users to have smaller binaries and better encapsulation in
their wasm32-unknown-unknown modules.
It's possible that this change will require existing wasm32-unknown-unknown
users will to add explicit `#[export_name = "..."]` directives to
exporrt the symbols that their programs depend on having exported.
rustdoc: remove redundant CSS `.import-item .stab { font-size }`
This sets the exact same font size that `.stab` has by default anyway. It used to be slightly different, but dd5ff428ed made it identical.
Build the profiler runtime to allow using -C profile-generate and -C instrument-coverage on POWER systems.
I have verified locally that the runtime builds and the profiler is working fine on the platform.

Several codegen tests are currently failing due to making
assumptions that are not valid for the s390x architecture:
- catch-unwind.rs: fails due to inlining differences.
Already ignored on another platform for the same reason.
Solution: Ignore on s390x.
- remap_path_prefix/main.rs: fails due to different alignment
requirement for string constants.
Solution: Do not test for the alignment requirement.
- repr-transparent-aggregates-1.rs: many ABI assumptions.
Already ignored on many platforms for the same reason.
Solution: Ignore on s390x.
- repr-transparent.rs: no vector ABI by default on s390x.
Already ignored on another platform for a similar reason.
Solution: Ignore on s390x.
- uninit-consts.rs: hard-coded little-endian constant.
Solution: Match both little- and big-endian versions.
Fixes part of https://github.com/rust-lang/rust/issues/105383.
Remove outdated syntax from trait alias pretty printing
Given the following program:
```rust
#![feature(trait_alias)]
trait A = ?Sized;
fn main() {}
```
Old output of `rustc +nightly ./t.rs -Zunpretty=normal`:
```rust
#![feature(trait_alias)]
trait A for ? Sized ;
fn main() {}
```
New output of `rustc +a ./t.rs -Zunpretty=normal`:
```rust
#![feature(trait_alias)]
trait A = ?Sized;
fn main() {}
```

Cleanup macro-expanded code in `rustc_type_ir`
We could of course just leave this as-is, but every time I go-to-def to this file it's painful to see all this `(&A(ref __self_1_0),)` stuff.
Point at args in associated const fn pointers
Tiny follow-up to #105201, not so sure it's worth it but 🤷
The UI test example is a bit more compelling when it's `GlUniformScalar::FACTORY`
