In #101230, the internal diagnostic migration lints -
`diagnostic_outside_of_impl` and `untranslatable_diagnostic` - were
modified so that they wouldn't trigger on functions annotated with
`#[rustc_lint_diagnostics]`. However, this change has to make it into
the bootstrap compiler before the `#[allow]` annotations that it aims to
remove can be removed, which is possible now that #102051 has landed.

macros: diagnostic derive on enums
Part of #100717.
Extends `#[derive(Diagnostic)]` to work on enums too where each variant acts like a distinct diagnostic - being able to represent diagnostics this way can be quite a bit simpler for some parts of the compiler.

LLVM 15 added `Optional::has_value`, and LLVM `main` (16) has deprecated
`hasValue`. However, its `explicit operator bool` does the same thing,
and was added long ago, so we can use that across our full LLVM range of
compatibility.
rustdoc: merge CSS `table` rules into `.docblock`
This was added in 510107815f, to fix the display of the module items and search results tables (see the discussion in https://github.com/rust-lang/rust/pull/86725).
Those aren't tables any more. The only remaining table is in docblock, which has its own padding declarations.

Allow more `!Copy` impls
You can already implement `!Copy` for a lot of types (with `#![feature(negative_impls)]`). However, before this PR you could not implement `!Copy` for ADTs whose fields don't implement `Copy` which didn't make any sense. Further, you couldn't implement `!Copy` for types impl'ing `Drop` (equally nonsensical).

Fixes#101836.

Fix lint scoping for let-else.
The scoping for let-else is inconsistent with HIR nesting. This creates cases, in `ui/let-else/let-else-allow-unused.rs` for instance, where an `allow` lint attribute does not apply to the bindings created by `let-else`.
This PR is an attempt to correct this.
As there is no lint that currently relies on this, the test for this behaviour is https://github.com/rust-lang/rust/pull/101500.

Those aren't tables any more. The only remaining table is in docblock, which
needs this attribute to look right.
