    M clang/test/SemaCXX/attr-lifetimebound.cpp

  Log Message:
  -----------
  [clang] Informative error for lifetimebound in decl-spec (#118567)

Emit a bit more informative error when the `[[clang::lifetimebound]]`
attribute is wrongly appearing on a decl-spec:

```
'lifetimebound' attribute only applies to parameters and implicit
object parameters
```

instead of:

```
'lifetimebound' attribute cannot be applied to types
```

The new error is also consistent with the diagnostic emitted when the
attribute is misplaced in other parts of a declarator.
