  -----------
  [SelectionDAG] Widen <2 x T> vector types for atomic store (#197618)

Vector types of 2 elements must be widened. This change does this
for vector types of atomic store in SelectionDAG so that it can
translate aligned vectors of >1 size.

Store-side counterpart to #148897. Stacked on top of #197166; and below
of #197619.
