[8u] RFR 8154945: Enable 8130150 and 8081778 intrinsics by default

[Vladimir Kempik]

Hello

Please review this simple change for jdk8u.

This patch makes intrinsics introduced in 8130150 and 8081778 to be 
enabled by default.

Basically it reverts https://bugs.openjdk.java.net/browse/JDK-8151522 
(without revering test changes of 8151522)


Bug: https://bugs.openjdk.java.net/browse/JDK-8154945
Webrev: http://cr.openjdk.java.net/~vkempik/8154945/webrev.00/

Thanks
