This just adds a clause to make it more obvious that the vector_size
attribute extension works with typedefs.
Note this whole section needs a rewrite to be a similar format as other
extensions. But that is for another day.
OK?

* doc/extend.texi (Using Vector Instructions): Add that
the base_types could be a typedef of them.

floating scalars, although arrays, pointers, and function return values
