[Dmitry Chuyko]

Hello,

Re-sending this to hotspot-dev on the advice of Adrew, the patch is 
updated for consolidated repo.

rfe: https://bugs.openjdk.java.net/browse/JDK-8186671
webrev: http://cr.openjdk.java.net/~dchuyko/8186671/webrev.01/
original thread: 
http://mail.openjdk.java.net/pipermail/aarch64-port-dev/2017-August/004870.html

The function was moved to platform .S file and now implemented with 
yield instruction.

I can do it, but it really needs to be sent to hotspot-dev.

OK, but without any actual implementations we can test it'll be a very
short discussion.
