[AArch64] Use 16 bytes as preferred function alignment on Cortex-A72. Summary: This change gives a 0.34% speed on execution time, a 0.61% improvement in benchmark scores and a 0.57% increase in binary size on a Cortex-A72. These numbers are the geomean results on a wide range of benchmarks from the test-suite, SPEC2000, SPEC2006 and a range of proprietary suites. The software optimization guide for the Cortex-A72 recommends 16 byte branch alignment.
