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.
Add slice to the stack allocated string comment
Precise that the "stack allocated string" is not a string but a string slice.

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.

Rustdoc-Json: Add tests for linking to foreign variants.
I initially taught these would be bugs, but it turn out they work perfectly, and the variant is added to paths.
Most of the work is done by jsondoclint checking all the ID's resolve (although this wont happen for links until #105015, which in turn is blocked on removing foreign traits), but we do check that neither the enum nor the variant is inlined, so it must be resolved correctly through paths.

rustdoc: remove `fnname` CSS class that's styled exactly like `fn`
It's not obvious why this was ever a separate class name, since even in c4219a4783 when it was first added, it was styled identically to regular `fn` links.

Document more settings for building rustc for Fuchsia
This documents that you need to link for Fuchsia with `lld` and provides configuration settings for both `clang` and `lld`. It also adjusts the documentation for running the test suite to recommend installing to a prefix.

Assign myself for docs updates

It's not obvious why this was ever a separate class name, since even
in c4219a4783 when it was first added,
it was styled identically to regular `fn` links.
`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.

Update VecDeque implementation to use head+len instead of head+tail
(See #99805)
This changes `alloc::collections::VecDeque`'s internal representation from using head and tail indices to using a head index and a length field. It has a few advantages over the current design:
* It allows the buffer to be of length 0, which means the `VecDeque::new` new longer has to allocate and could be changed to a `const fn`
* It allows the `VecDeque` to fill the buffer completely, unlike the old implementation, which always had to leave a free space
* It removes the restriction for the size to be a power of two, allowing it to properly `shrink_to_fit`, unlike the old `VecDeque`
* The above points also combine to allow the `Vec<T> -> VecDeque<T>` conversion to be very cheap and guaranteed O(1). I mention this in the `From<Vec<T>>` impl, but it's not a strong guarantee just yet, as that would likely need some form of API change proposal.
All the tests seem to pass for the new `VecDeque`, with some slight adjustments.

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.
