Rename and allow `cast_ref_to_mut` lint
This PR is a small subset of https://github.com/rust-lang/rust/pull/112431, that is the renaming of the lint (`cast_ref_to_mut` -> `invalid_reference_casting`).
BUT also temporarily change the default level of the lint from deny-by-default to allow-by-default until https://github.com/rust-lang/rust/pull/112431 is merged.

I could not find a test for this particular use case. The closest I got
was `tests/ui/imports/issue-37887.rs`, but that is a regression test
for a different use case.
fix(resolve): update the ambiguity glob binding as warning recursively
Fixes#47525Fixes#56593, but `issue-56593-2.rs` is not fixed to ensure backward compatibility.
Fixes#98467Fixes#105235Fixes#112713
This PR had added a field called `warn_ambiguous` in `NameBinding` which is only for back compatibly reason and used for lint.

tests/ui/proc-macro/*: Migrate FIXMEs to check-pass
proc-macros are processed early in the compiler pipeline. There is no need to involve codegen. So change to check-pass.
I have also looked through each changed test and to me it is sufficiently clear that codegen is not needed for the purpose of the test.
I skipped changing `tests/ui/proc-macro/no-missing-docs.rs` in this commit because it was not clear to me that it can be changed to check-pass.

Add regression test for `--cap-lints allow` and trait bounds warning
Closes#43134
I have verified that the test fails if stderr begins to contain output by making sure the test fails when I add
eprintln!("some output on stderr");
to the compiler (I added it to `fn build_session()`).
Skip reporting item name when checking RPITIT GAT's associated type bounds hold
Doesn't really make sense to label an item that has a name that users can't really mention. Fixes#114145. Also fixes#113794.

privacy: no nominal visibility for assoc fns
Fixes#113860.
When `staged_api` is enabled, effective visibilities are computed earlier and this can trigger an ICE in some cases.
In particular, if a impl of a trait method has a visibility then an error will be reported for that, but when privacy invariants are being checked, the effective visibility will still be greater than the nominal visbility and that will trigger a `span_bug!`.
However, this invariant - that effective visibilites are limited to nominal visibility - doesn't make sense for associated functions.
Diagnostic namespace
This PR implements the basic infrastructure for accepting the `#[diagnostic]` attribute tool namespace as specified in https://github.com/rust-lang/rfcs/pull/3368. Note: This RFC is not merged yet, but it seems like it will be accepted soon. I open this PR early on to get feedback on the actual implementation as soon as possible. This hopefully enables getting at least the diagnostic namespace to stable rust "soon", so that crates do not need to bump their MSRV if we stabilize actual attributes in this namespace.
This PR only adds infrastructure accept attributes from this namespace, it does not add any specific attribute. Therefore the compiler will emit a lint warning for each attribute that's actually used. This namespace is added behind a feature flag, so it will be only available on a nightly compiler for now.
cc `@estebank` as they've supported me in planing, specifying and implementing this feature.

Move two tests from `tests/ui/std` to `library/std/tests`
Hi, there,
This pull request comes from this issue (#99417), sorry I made some mistakes creating the pull request, it's my first one.
Regression test `println!()` panic message on `ErrorKind::BrokenPipe`
No existing test (that I could find) failed if the `panic!()` of the `println!()` family of functions was removed, or if its message was changed:
104f4300cf/library/std/src/io/stdio.rs (L1007-L1009)
So add such a test.
This is in preparation of adding a hint about the existence of [`unix_sigpipe`](https://github.com/rust-lang/rust/issues/97889) if that is the reason for the panic.
Even if we don't end up adding a hint, this is still a sensible test to have, I think.
