[AArch64] Use 8 bytes as preferred function alignment on Cortex-A53.
Summary:
This change gives a 0.25% speedup on execution time, a 0.82% improvement
in benchmark scores and a 0.20% increase in binary size on a Cortex-A53.
These numbers are the geomean results on a wide range of benchmarks from
the test-suite and a range of proprietary suites.
