Hi Patric,

Do you need Graal changes for this? Or it already has these intrinsics 
and the only problem is these flags were not set in vm_version_x86.cpp?

Small note. In vm_version_x86.cpp previous code has already 
COMPILER2_OR_JVMCI check. You can remove previous #endif and new #ifdef. 
Also change comment for closing #endif at line 1080 to // COMPILER2_OR_JVMCI

1080 #endif // COMPILER2

What testing you did?
