As with JDK-8165231 for ppc64[be,le], the aarch64 port in aarch64/jdk8u supports unaligned memory access, but the tests in sun/security/provider/ByteArrayAccess.java and src/share/classes/java/nio/Bits.java don't include it. We should add it.

This is inapplicable for 9 as it has the superior fix, JDK-8026049.
