RFR: 8153655: Make intrinsics flags diagnostic and update intrinsics tests to enable diagnostic options.

[Rahul Raghavan]

Hi,

Thank you Vladimir for review comments.
Yes, now updated the changes.

Please review following revised webrev -
http://cr.openjdk.java.net/~rraghavan/8153655/webrev.01/
(Modified 'test/compiler/intrinsics/sha/cli/testcases/GenericTestCaseForUnsupportedX86CPU.java')

No issues found with testing done using product builds with proposed changes
(hotspot/test/compiler/cpuflags/*, hotspot/test/compiler/intrinsics/* etc.)
Complete pre-integration testing using product builds is in progress for this 'webrev.01'.
(No issues with pre-integration testing done earlier for 'webrev.00'.)

Thanks,
Rahul
