Refactor + improve diagnostics for `&mut T`/`T` mismatch inside Option/Result
Follow up to #114052. This also makes the diagnostics structured + translatable.

Change LLVM BOLT flags
I talked to the BOLT maintainers about the binary size effect of BOLT. Currently, BOLTing LLVM increases its binary size from ~120 MiB to ~170 MiB, which is not ideal. Now we can track both runtime performance and (rustc, LLVM, ...) artifact sizes in perf.RLO, so I'd like to try experimenting with changing the flags to reduce `libLLVM.so` size without regressing the performance gains of BOLT too much.

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.

Fix issue_15149 test for the SGX target
PR https://github.com/rust-lang/rust/pull/112390 moved tests to std. Unfortunately, this caused the `issue_15149` test to be enabled for the SGX target. This is incorrect as the SGX target does not support the `env::current_exe()` call.
Fix switch-stdout test for none unix/windows platforms
PR #112390 moved tests to std. Unfortunately, there is a typo which causes issues on platforms other than unix and windows.
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()`).
Replace a lazy `RefCell<Option<T>>` with `OnceCell<T>`
This code was using `RefCell<Option<T>>` to manually implement lazy initialization. Now that we have `OnceCell` in the standard library, we can just use that instead.
In particular, this avoids a confusing doubly-nested option, because the value being lazily computed is itself an `Option<Symbol>`.
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.
r? `@spastorino`
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.
