[RFR} [8u] JDK-8228440: TestAESCiphers tests fail with "access denied" trying to access ArrayUtil

[Andrew John Hughes]

Webrev: https://cr.openjdk.java.net/~andrew/openjdk8/8228440/webrev.01/
Bug: https://bugs.openjdk.java.net/browse/JDK-8228440

This cleans up the backport of JDK-8179098 by moving the new ArrayUtil
methods (inside a new class, RangeUtil) and the Preconditions class into
the com.sun.crypto.provider class that makes use of them, avoiding the
need for such checks to cross two package boundaries (sun.security.util
& jdk.internal.util)

Ok to push?

Thanks,
