[61/77] Use scalar_int_mode in the AArch64 port
This patch makes the AArch64 port use scalar_int_mode in various places.
Other ports won't need this kind of change; we only need it for AArch64
because of the variable-sized SVE modes.
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.
