  [SelectionDAG] Split vector types for atomic store (#197860)

Vector types that aren't widened are split so that a single ATOMIC_STORE
is issued for the entire vector at once. This enables SelectionDAG to
translate vectors with type bfloat,half.

Store-side counterpart to #165818. Stacked on top of #197619; and below
of #197861.
