[51/77] Use opt_scalar_int_mode when iterating over integer modes
This patch uses opt_scalar_int_mode rather than machine_mode
when iterating over scalar_int_modes, in cases where that helps
with future patches. (Using machine_mode is still OK in places
that don't really care about the mode being a scalar integer.)

gcc/
* cse.c (cse_insn): Use opt_scalar_int_mode for the mode iterator.
* explow.c (hard_function_value): Likewise.
* expmed.c (extract_fixed_bit_field_1): Likewise. Move the
convert_to_mode call outside the loop.
* expr.c (alignment_for_piecewise_move): Use opt_scalar_int_mode
for the mode iterator. Require the mode specified by max_pieces
to exist.
(emit_block_move_via_movmem): Use opt_scalar_int_mode for the
mode iterator.
(copy_blkmode_to_reg): Likewise.
(set_storage_via_setmem): Likewise.

* trans-types.c (gfc_init_kinds): Use opt_scalar_int_mode for
the mode iterator.
