8251216: Implement MD5 intrinsics on AArch64

[phohensee]

This backport completes the series whose prefix is JDK-8250902 and JDK-8251260. See https://git.openjdk.java.net/jdk15u-dev/pull/163 and https://git.openjdk.java.net/jdk15u-dev/pull/166 respectively.

The backport is clean except for a minor conflict in stubRoutines_aarch64.hpp, where code_size2 is changed to 45000.

Testing: tier1, including MD5/SHA jtreg tests.

Looks good to me. The new code size is probably a little to high because in 18 there are additional stubs which haven't been downported yet, but better be on the safe side :)

That's what I thought too. Also, it's a tiny bit less different from the original patch to leave it at 45000. Thanks for the review!

[phohensee]

Approved.
