Change the logic such that linking from a public to a private item always
triggers intra_doc_link_resolution_failure. Previously, the warning was
not emitted when --document-private-items is passed.
Also don't rely anymore on the item's visibility, which would falsely trigger
the lint now that the check for --document-private-items is gone.
Disable polymorphisation
Fixes#74614.
This PR disables polymorphisation to fix the regression in #74614 after investigation into the issue makes it clear that the fix won't be trivial. ~~I'll file an issue shortly to replace #74614 with the findings so far.~~ #74636 has been filed to track the fix of the underlying regression.

Apply #66379 to `*mut T` `as_ref`
#66379 changed the documentation of `as_ref` on the type `*const T` and `as_mut` on the type `*mut T`, but it missed making that same change for `as_ref` on the type `*mut T`.
refactor and reword intra-doc link errors
This commit refactors intra-doc link error reporting to deduplicate code
and decouple error construction from the type of error. This greatly
improves flexibility at each error construction site, while reducing the
complexity of the diagnostic creation.
This commit also rewords the diagnostics for clarity and style:
- Diagnostics should not end in periods.
- It's unnecessary to say "ignoring it". Since this is a warning by
default, it's already clear that the link is ignored.
Stabilize control-flow-guard codegen option
This is the stabilization PR discussed in #68793. It converts the `-Z control-flow-guard` debugging option into a codegen option (`-C control-flow-guard`), and changes the associated tests.
This commit disables polymorphisation to resolve regressions related to
closures which inherit unused generic parameters and are then used in
casts or reflection.

This commit changes the span and content of the "collection encountered
polymorphic constant" bug in monomorphization collection to point to the
use of the constant rather than the definition.

Disable Azure Pipelines except for macOS
Following up on https://github.com/rust-lang/rust/pull/74565, this PR disables most of Azure Pipelines except for macOS auto builds, practically switching us to GitHub Actions 🎉

This adds a dedicated branch for perf to use for CI, intended to allow perf to
enqueue builds without needing to use bors. bors is great, but bors requires an
open PR to work, and we want to invoke perf on closed PRs sometimes (in
particular, rollups).
[AVR] Correctly set the pointer address space when constructing pointers to functions
NOTE: Pull request iterations:

This patch extends the existing `type_i8p` method so that it requires an
explicit address space to be specified. Before this patch, the
`type_i8p` method implcitily assumed the default address space, which is
not a safe transformation on all targets, namely AVR.
The Rust compiler already has support for tracking the "instruction
address space" on a per-target basis. This patch extends the code
generation routines so that an address space must always be specified.
In my estimation, around 15% of the callers of `type_i8p` produced
invalid code on AVR due to the loss of address space prior to LLVM final
code generation. This would lead to unavoidable assertion errors
relating to invalid bitcasts.
With this patch, the address space is always either 1) explicitly preserved
from the input type, or 2) explicitly set to the instruction address
space because the logic is dealing with functions which must be placed
there, or 3) explicitly set to the default address space 0 because the
logic can only operate on data space pointers and thus we keep the
existing semantics of assuming the default, "data" address space.
Fix rust-src component.
The rust-src component could not be installed by rustup because it included some symbolic links. #74520 added the backtrace directory which included some symlinks. Since the rust-src component doesn't need most of the files in the `backtrace` submodule, this changes it to only include the minimum necessary.
Tested with cargo's build-std that it can build from the resulting tarball.
Fixes#74577
Upload builds from GHA instead of Azure Pipelines
This PR does two things:
* Enables RLA comments on PRs (needed after the switch to GHA in RLA).
* Switches GitHub Actions as the CI authorized to upload non-macOS builds.
Note that Docker/LLVM caches will likely be busted.

Now that #74163 updated the minimum Linux kernel to 2.6.32, we can
assume the availability of APIs that open file descriptors that are
already set to close on exec, including the flags `O_CLOEXEC`,
`SOCK_CLOEXEC`, and `F_DUPFD_CLOEXEC`.
