interpret: remove outdated FIXME
The rule about `repr(C)` types with compatible fields got removed from the ABI compat docs before they landed, so this FIXME here is no longer correct. (So this is basically a follow-up to https://github.com/rust-lang/rust/pull/130185, doing some more cleanup around deciding not to guarantee ABI compatibility for structurally compatible `repr(C)` types.)
Refactor fd read/write
This PR passed the responsibility of reading to user supplied buffer and dest place to each implementation of ``FileDescription::read/write/pread/pwrite``.
This is part of #3665.
Mark `char::make_ascii_uppercase` and `char::make_ascii_lowercase` as const.
Relevant tracking issue: #130698
The `make_ascii_uppercase` and `make_ascii_lowercase` methods in `char` should be marked "const."
With the stabilisation of [`const_mut_refs`](https://github.com/rust-lang/rust/issues/57349/), this simply requires adding the `const` specifier to the function signatures.
fix rustc_nonnull_optimization_guaranteed docs
As far as I can tell, even back when this was [added](https://github.com/rust-lang/rust/pull/60300) it never *enabled* any optimizations. It just indicates that the FFI compat lint should accept those types for NPO.

tests: Test that `extern "C" fn` ptrs lint on slices
This seems to have slipped past the `improper_ctypes_definitions` lint at some point. I found similar tests but not one with this exact combination, so test the semi-unique combination.
Prevent Deduplication of `LongRunningWarn`
Fixes#118612
As mention in the issue, `LongRunningWarn` is meant to be repeated multiple times.
Therefore, this PR stores a unique number in every instance of `LongRunningWarn` so that it's not hashed into the same value and omitted by the deduplication mechanism.
Fixup Apple target's description strings
Noticed this inconsistency in how the Apple target's had their new descriptions written while looking at https://github.com/rust-lang/rust/pull/130614, and figured it was easy enough to fixup shortly. I think prefixing every OS with `Apple` is clearer, especially for less known ones like `visionOS` and `watchOS`; so that's what was done here along with making the architecture names more consistent and then some other small tweaks.
