Log:
Use scalar_(int_)mode in the AArch64 port

This patch makes the AArch64 port use scalar_mode and
scalar_int_mode in various places.  Other ports won't need
this kind of change; we only need it for AArch64 because of
the polynomial integers that are added by later patches.

The only change in functionality is in the rtx_costs handling
of CONST_INT.  If the caller doesn't supply a mode, we now pass
word_mode rather than VOIDmode to aarch64_internal_mov_immediate.
aarch64_movw_imm will therefore not now truncate large constants
in this situation.
