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
This sets myself as the reviewer for docs submodule updates. Now with https://github.com/rust-lang/triagebot/pull/1673 automating the process, this piece of the puzzle handles the assignment step.

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.
Fixes https://github.com/rust-lang/rust/issues/104815

Add documentation for `has_escaping_bound_vars`
Thanks to `@BoxyUwU` for explaining this to me. Adding docs with a helpful link if people get confused.
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.

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.
Remove Crate::primitives field
It is a new approach to #90447. Instead of removing primitives from everywhere (ie from `BadImplStripper`), I just removed them from the `Crate` type, allowing to reduce its size.

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.
Rustup
No changes happened on the rustc side, but I want to do a push next and would rather make josh's life easier by integrating some recent history first.
