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.

x86/cpufeature: Add AVX512_4VNNIW and AVX512_4FMAPS features AVX512_4VNNIW - Vector instructions for deep learning enhanced word variable precision. AVX512_4FMAPS - Vector instructions for deep learning floating-point single precision. These new instructions are to be used in future Intel Xeon & Xeon Phi processors. The bits 2&3 of CPUID[level:0x07, EDX] inform that new instructions are supported by a processor. The spec can be found in the Intel Software Developer Manual (SDM) or in the Instruction Set Extensions Programming Reference (ISE). Define new feature flags to enumerate the new instructions in /proc/cpuinfo accordingly to CPUID bits and add the required xsave extensions which are required for proper operation.
