Until now, all data arguments to a scatter store needed to have
32-bit or 64-bit elements. This isn't true for the upcoming SVE2.1
svst1q scatter intrinsic, so this patch adds an abstraction around the
restriction.

(store_scatter_base::infer_vector_type): New virtual member function.
(store_scatter_base::resolve): Use it.
