I've since learned that the mapping between libc fds and wasi fds are
expected to be one-to-one, so we can use the raw syscalls for writing to
stdout/stderr and reading from stdin! This should help ensure that we
don't depend on a C library too unnecessarily.
This commit switches the wasi target to loading CLI arguments via the
syscalls provided by wasi rather than through the argc/argv passed to
the main function. While serving the same purpose it's hoped that using
syscalls will make us a bit more portable (less reliance from libstd on
an external C library) as well as avoiding the need for a lock!
Optimize indentation in the pretty printer.
Currently the pretty-printer calls `write!` for every space of
indentation. On some workloads the indentation level can exceed 100, and
a faster implementation reduces instruction counts by up to 7% on a few
workloads.

Fix LLVM IR generated for C-variadic arguments
It is possible to create malformed LLVM IR given variadic arguments that
are aggregate types. This occurs due to improper tracking of the current
argument in the functions list of arguments.
Fixes: #58881

Remove #[doc(hidden)] from Error::type_id
Nominating this for beta so that `Error::type_id` has documentation in time for release.

Stabilize refcell_replace_swap feature
Please be kind, this is my first time contributing. 😄
I noticed #43570 only needs stabilizing (and I need it for a side project I'm working on), so I followed the [guide](https://rust-lang.github.io/rustc-guide/stabilization_guide.html#stabilization-pr) to move things forward.
I'm happy to amend things if needed, let me know!
rustc_target: factor out common fields of non-Single Variants.
@tmandry and I were discussing ways to generalize the current variants/discriminant layout to allow more fields in the "`enum`" (or another multi-variant types, such as potentially generator state, in the future), shared by all variants, than just the tag/niche discriminant.
This refactor should make it easier to extend multi-variant layouts, as nothing is duplicating anymore between "tagged enums" and "niche-filling enums".

Changed reference style in dbg macro docs.
# Description
A continuation of Pull Request #59528 :
- Fixed method of referencing and adjusted the references as suggested by @lzutao
doc: use correct body font URLs
The CSS for the docs homepage (docs.rust-lang.org) was using the wrong
URL for the body font, resulting in the fallback serif font being used,
instead of the desired Source Serif Pro fonts.
(It's worth noting that the CSS for rustdoc's API generation got these URLs right.)
