Corrected a typo in the explanation of inferred arguments in ambig AST positions.

Fix typo in ambig AST positions description

Because that's what it is: any type with tokens must also have attrs. This simplifies some trait bounds.

…ctions When a const function drops a value whose type is a type parameter, suggest adding a `[const] Destruct` bound so the destructor can be evaluated at compile-time.

The suggested bound requires the unstable `const_destruct` feature, so it is not actionable on a stable compiler. Add a run-make test that verifies the suggestion is only emitted on nightly.

This way codegen backends don't have to check for a magic symbol name prefix to detect LLVM intrinsic calls and thus can more easily handle them separately as necessary.

This optimisation is currently broken on s390x[^1]. It looks like a big-endian issue in general. but as we only know about the test fails on s390x we only disable it there. Should be reenabled when the problem is fixed and llvm backend is updated. [^1]: llvm/llvm-project#208712

remove obsolete comment This was a reminder to make the lint translatable, but the code to make lints translatable has since been removed

…nszelmann Construct `tokens` for attrs made by `mk_attr_word` and other variants Fixes rust-lang#159261 `tokens` won't be constructed for generated built-in attrs before, so that after rust-lang#158854, `#[rustc_test_entrypoint_marker]` without `tokens` would be added when expanding `#[test]`. Then later expansions would cause the ICE when they wanna get the attr's `tokens`. This PR makes `tokens` constructed for such attrs, although this specific ICE only need editing `mk_attr_word`, but I think it would be good to also edit `mk_attr_nested_word` and `mk_attr_name_value_str`.

…ion-verbose, r=mejrs Remove obsolete verbose flag from deref/ref suggestions
