Change cpu for vptestnmd and vptestnmq instructions.

Change cpu for vptestnmd and vptestnmq instructions.

In latest release of AVX512 spec
http://download-software.intel.com/sites/default/files/managed/50/1a/319433-018.pdf
Vptestnmq and vptestnmq instructions have CPUID AVX512F, not AVX512CD.
This patch fixes it.
