The entries in the intrinsics lists need to be ordered (running `mx unittest CheckGraalIntrinsics` will show the issue).

Internal changes have been prepared.

> Note, JDK 9 will be updated soon [2] to get the same renaming so Graal-core does not need to check for JDK 10 specifically. But changes should be pushed only after [2] is pushed into jdk9/dev and get into promoted build which people use with Graal.

> I looked on other places in Graal where such methods are used and they are from sun.misc.Unsafe class. Those places have to be fixed too when sun.misc.Unsafe become obsolete.
