Is there a compelling reason for memory to be allocated before VecSetUp()?
Deferring it would make it easier to specify what memory to use or specify
ghosting in any order.

My preference is that ghosting is orthogonal to type, to the extent that it
would make sense for the storage format (non-contiguous AMR grids might not
be).
