RFA: PATCH to reconstruct_complex_type to preserve attributes

[Jason Merrill]

While working on c++/9381 I noticed this as another place we were
rebuilding types but not preserving attributes.  OK for trunk?

Tested x86_64-pc-linux-gnu, applied to trunk.

I guess it doesn't matter much - the only user seems to be
handle_vector_size_attribute.  But ok anyway.

Thanks.
