Add QEMU test for x86_64-unknown-uefi
The UEFI targets don't have std support yet, so the normal tests don't work. However, we can compile a simple no-std program and run it under QEMU to at least check that the target compiles, links, and runs.
Tested locally with: `src/ci/docker/run.sh x86_64-uefi`

Fix ICE when negative impl is collected during eager mono
```rust
trait Foo {
fn foo() {}
}
impl !Foo for () {}
```
This code will currently cause an ICE when mono collection mode is "eager" (with `-C link-dead-code=y` or `-Z print-mono-items=eager`.
Remove rustdoc clean::Visibility type
Fixes#90852.
Follow-up of https://github.com/rust-lang/rust/pull/103690.
This PR completely removes the rustdoc `clean::Visibility` type to use the `rustc_middle` one instead. I don't think there will be any impact on perf.

Fix late-bound lifetime closure ICEs in HIR typeck and MIR borrowck
During HIR typeck, we need to teach astconv to treat late-bound regions within a closure body as free, fixing escaping bound vars ICEs in both of the issues below.
However, this then gets us to MIR borrowck, which itself needs to be taught how to instantiate free region vids for late-bound regions that come from items that _aren't_ the typeck root (for now, just closures).

asm: Match clang behavior for inlateout fixed register operands
We have 2 options for representing LLVM constraints for `inlateout` operands on a fixed register (e.g. `r0`): `={r0},0` or `={r0},{r0}`.
This PR changes the behavior to the latter, which matches the behavior of Clang since https://reviews.llvm.org/D87279.
rustdoc: remove no-op CSS `#main-content > .item-info { margin-top: 0 }`
When this line was added in 04b4c40682c01cad8f9bc8d5b3907be91d6f81d4, it overrode a negative `margin-top` that was set on it by default.
04b4c40682/src/librustdoc/html/static/rustdoc.css (L500-L516)
That negative top margin was removed in 593d6d1cb15c55c88319470dabb40126c7b7f1e2.
Add howto for adding new targets
When new targets are added, often a reviewer finds out that e.g. the target-3-tier-policy is not filled out (missing), there is no description etc.
This change adds a description of what I've learned while working on #102701. It should make reviews easier in the future with less rework.

Add visit_fn_ret_ty to hir intravisit
I'm working on some RPITIT changes and I need to specialize `visit_fn_ret_ty` in my visitor impl. So I guess it's better to land it separately.

FIX - StrippingDebugInfoFailed typo
DELETE - unneeded FIXME comment
UPDATE - only declare the error with ExtractBundledLibsError as an enum and use the Diagnostic derive macro
It deals with eight cases: ints, floats, and the six quoted types
(char/byte/strings). For ints and floats we have an early return, and
the other six types fall through to the code at the end, which makes the
function hard to read.
This commit rearranges things to avoid the early returns.
There are three kinds of "byte" literals: byte literals, byte string
literals, and raw byte string literals. None are allowed to have
non-ASCII chars in them.
Two `EscapeError` variants exist for when that constraint is violated.
- `NonAsciiCharInByte`: used for byte literals and byte string literals.
- `NonAsciiCharInByteString`: used for raw byte string literals.
As a result, the messages for raw byte string literals use different
wording, without good reason. Also, byte string literals are incorrectly
described as "byte constants" in some error messages.
This commit eliminates `NonAsciiCharInByteString` so the three cases are
handled similarly, and described correctly. The `mode` is enough to
distinguish them.
Note: Some existing error messages mention "byte constants" and some
mention "byte literals". I went with the latter here, because it's a
more correct name, as used by the Reference.
