[Sander de Smalen via Phabricator via cfe-commits]

sdesmalen added a comment.

- Limited attribute to GNU spelling __attribute__((...))
- Changed `arm_locally_streaming` attribute to be `DeclOrStmtAttr` because it does not apply to type (only the definition)
- Changed the other SME attributes to be `TypeAttr`.
- Added checks and new tests for conflicting attributes on redeclarations
- Added checks and new tests for conflicting attributes on virtual function overrides
- Added new tests for propagation of type attributes on other declarations using `decltype(otherty)`
