Piotr Luc 06b35d93af x86/cpufeature: Add AVX512_VPOPCNTDQ feature 
Vector population count instructions for dwords and qwords are going to be
available in future Intel Xeon & Xeon Phi processors. Bit 14 of
CPUID[level:0x07, ECX] indicates that the instructions are supported by a
processor.

The specification can be found in the Intel Software Developer Manual (SDM)
and in the Instruction Set Extensions Programming Reference (ISE).

Populate the feature bit and clear it when xsave is disabled.
