[30/77] Use scalar_int_mode for doubleword splits
This patch uses is_a <scalar_int_mode> in a couple of places that
were splitting doubleword integer operations into word_mode
operations. It also uses scalar_int_mode in the expand_expr_real_2
handling of doubleword shifts.

* expr.c (expand_expr_real_2): Use scalar_int_mode for the
double-word mode.
* lower-subreg.c (resolve_shift_zext): Use is_a <scalar_int_mode>.
* optabs.c (expand_unop): Likewise.
