Print all features with --print target-features
This fixes `rustc --print target-features` with respect to aliases and tied features.
Before this change, the print command assumed that each LLVM feature corresponds exactly to one rustc feature. In the case of aliases and tied features, this assumption failed and some features (such as aarch64's "pacg") were missing. With this change, every target feature is listed.
type alias impl trait: add tests showing that hidden type only outlives lifetimes that occur in bounds
fixes#103642https://github.com/rust-lang/rust/pull/102417 only made sure that hidden types cannot outlive lifetimes other than the ones mentioned on bounds, but didn't allow us to actually infer anything from that.

`mk_const(ty::ConstKind::X(...), ty)` can now be simplified to
`mk_cosnt(..., ty)`.
I searched with the following regex: \mk_const\([\n\s]*(ty::)?ConstKind\
I've left `ty::ConstKind::{Bound, Error}` as-is, they seem clearer this
way.
- Accept `impl Into`
- Implement `From<>` for `ConstKind`
Note: this adds a dependency on `derive_more` (MIT license). It allows
to derive a lot of traits (like `From` here) that would be otherwise
tedious to implement.
stricter alignment enforcement for ScalarPair
`@eddyb` [indicated](https://github.com/rust-lang/rust/pull/103926#discussion_r1033315005) that alignment violating this check might be a bug. So let's see what the test suite says.
(Only the 2nd commit actually changes behavior... but I couldn't not do that other cleanup.^^)
Does the PR CI runner even enable debug assertions though...?
make simple check of prinf function
Fixes https://github.com/rust-lang/rust/issues/92898
With this commit we start to make some simple
check when the name resolution fails, and
we generate some helper messages in case the
name is a C name like in the case of the `printf`
and suggest the correct rust method.

Ignore bivariant parameters in test_type_match.
https://github.com/rust-lang/rust/pull/103491 made opaque types bivariant with respect of some of their lifetime parameters. Because of this bivariance, some lifetime variables were not unified to anything during borrowck, and were considered as unequal by borrowck type test.
This PR makes type test ignore the bivariant parameters in test_type_match.

Remove `SelectionContext::infcx()` in favor of field access
Encapsulation doesn't seem particularly important here, and having two choices is always more confusing than having one.

Change multiline span ASCII art visual order
Tweak the ASCII art for nested multiline spans so that we minimize line overlaps.
Partially addresses https://github.com/rust-lang/rust/issues/61017.
`Lit::from_included_bytes` calls `Lit::from_lit_kind`, but the two call
sites only need the resulting `token::Lit`, not the full `ast::Lit`.
This commit changes those call sites to use `LitKind::to_token_lit`,
which means `from_included_bytes` can be removed.
Prefer doc comments over `//`-comments in compiler
Doc comments are generally nicer: they show up in the documentation, they are shown in IDEs when you hover other mentions of items, etc. Thus it makes sense to use them instead of `//`-comments.

Pretty-print generators with their `generator_kind`
After removing `GenFuture`, I special-cased async generators to pretty-print as `impl Future<Output = X>` mainly to avoid too much diagnostics changes originally.
This now reverses that change so that async fn/blocks are pretty-printed as `[$async-type@$source-position]` in various diagnostics, and updates the tests that this touches.
