[8u] RFR 8151522: Disable 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 disabled by default.

They still can be enabled with proper flags.

I also had to modify testcases introduced by 8130150 and 8081778 to enable these flags.

Testing: jprt.

Bug: https://bugs.openjdk.java.net/browse/JDK-8151522
Webrev: http://cr.openjdk.java.net/~vkempik/8151522/webrev.00/

Thanks
