RFR (XS): 8165287: Bug fix for Compress intrinsic avx512

[Deshpande, Vivek R]

Hi Vladimir

I used skylake platform with EVEX support and performed the jtreg tests from hotspot/compiler and jdk/test/java/lang/String* along with SPCjvm2008 suite.

Regards,
Vivek

Hi Vivek,

Changes looks fine to me.

What testing you did? Since we don't have EVEX machines for out testing we are relying on you to run tests on these machines.

In addition to Hotspot jtreg tests please run, at least,
jdk/test/java/lang/String* tests too.

Thanks,
Vladimir
