[aarch64-port-dev ] RFR:8246051:[AArch64]SIGBUS by unaligned Unsafe compare_and_swap

[Wang Zhuo(Zhuoren)]

Updated the test. Not AArch64-only now.
http://cr.openjdk.java.net/~wzhuo/8246051/webrev.02/

BTW, the behavior of unaligned Unsafe swap on aarch64(throw InternalError) are different from on X86(do the swap). Not sure whether the difference makes sence.

Zhuoren

The test is AArch64-only but the patch is to shared code. This doesn't
make sense to me.
