Add vect_recog_cond_expr_convert_pattern.
The pattern converts (cond (cmp a b) (convert c) (convert d))
to (convert (cond (cmp a b) c d)) when
1) types_match (c, d)
2) single_use for (convert c) and (convert d)
3) TYPE_PRECISION (TREE_TYPE (c)) == TYPE_PRECISION (TREE_TYPE (a))
4) INTEGERAL_TYPE_P (TREE_TYPE (c))
The pattern can save packing of mask and data(partial for data, 2 vs
1).
