Hi Richard, Aaron,
This is a kind reminder if case this thread got forgotten.
Any thoughts on this?

> As far as I know, alignment attributes only appertain to variables or typedefs (which both have AST nodes). I don't think we can generalize this approach for vector_size attribute as it appertains to types (which do not have AST nodes).
> What about creating a new property for VectorType that would state that this vector type is dependent (dependent vector types are vector types with dependent base types and/or dependent size expressions)? It seems to be somewhat more appropriate to me.
> This will be somewhat similat to the way ExtVectorType and DependentSizedExtVectorType are treated.
> What do you think?
