Pass the base element type of an array type to the visit method instead

of the array type itself.

This fixes a bug found by inspection that was introduced in r353459. I
don't have a test case for this since we don't yet have types that would
make the containing C struct non-trivial to copy/move but wouldn't make
it non-trivial to default-initialize or destruct.
