Use intermediate instructions, unlike with buffer stores. This is
necessary because of the need to have an internal way to distinguish
between signed and unsigned extloads. This introduces some duplication
and near duplication with the buffer store selection path. The store
handling should maybe be moved into legalization to match and
eliminate the duplication.
