[AArch64] Minor rtx costs tweak
aarch64_rtx_costs uses the number of registers in a mode as the basis
of SET costs. This patch makes it get the number of registers from
aarch64_hard_regno_nregs rather than repeating the calcalation inline.
Handling SVE modes in aarch64_hard_regno_nregs is then enough to get
the correct SET cost as well.
