[AArch64] PR79262: Adjust vector cost
PR79262 has been fixed for almost all AArch64 cpus, however the example is still
vectorized in a few cases, resulting in lower performance. Adjust the vector
cost slightly so that so that -mcpu=cortex-a53 now has identical performance as
-mcpu=cortex-a57 on libquantum.
