The attached patch adds handling of dependent arguments to attribute aligned and attribute vector_size, fixing c++/58109 and 69022 - attribute vector_size ignored with dependent bytes.
In the longer term, Gaby used to suggest that internally we should represent the vector_size attribute as some kind of template __vector<scalar,size> (half-way between a template class and a template alias). The goal would be to avoid duplicating all the logic from templates into attributes.
Of course that's much more work (even assuming that there isn't some big road-block, which there might be), and a little bit more code duplication as in your patch seems appropriate at this stage.
