[74/77] Various small scalar_mode changes
This patch uses scalar_mode in a few miscellaneous places:
- Previous patches mean mode_to_vector can take a scalar_mode without
further changes.
- Implicit promotion is limited to scalar types (affects promote_mode
and sdbout_parms)

* machmode.h (mode_for_vector): Take a scalar_mode instead
of a machine_mode.
* stor-layout.c (mode_for_vector): Likewise.
* explow.c (promote_mode): Use as_a <scalar_mode>.
* sdbout.c (sdbout_parms): Use is_a <scalar_mode>.
