Fix linkage diagnostic so it doesn't ICE for external crates

Fix linkage diagnostic so it doesn't ICE for external crates

(As a drive-by improvement, improved the diagnostic to indicate *why* `*const T` or `*mut T` is required.)

Warn on bare_trait_objects by default

The `bare_trait_objects` lint is set to `warn` by default.
Most ui tests have been updated to use `dyn` to avoid creating noise in stderr files.

Fix ICE with struct ctors and const generics. 
This commit fixes a ICE where struct constructors were resulting in an
ICE with const generics. Previously, a `match` in `type_of` did not have
an arm for the `DefKind::Ctor` resolutions and therefore would assume
that the type did not have generics.

Rollup merge of #61024 - petrochenkov:proctest, r=nikomatsakis 
tests: Centralize proc macros commonly used for testing

Many proc macros in `ui\proc-macro\auxiliary` were doing same things.
(I added a fair share of those myself.)

Now commonly used macros (empty, identity, etc) are collected in one place - `ui\proc-macro\auxiliary\test-macros.rs`.

Special-case .llvm in mangler to fix segfaults 
This commit special cases `.llvm` in the mangler to print `.llvm$6d$`
instead. This will avoid segfaults when names in a user's Rust code are
`llvm`.

- Use consistend error message: "malformed `attrname` attribute input"
- Provide suggestions when possible
- Move note/help to label/suggestion
- Use consistent wording "ill-formed" -> "malformed"
- Move diagnostic logic out of parser
