AVX-VNNI-INT8 is a new set of instructions in the latest Intel platform Sierra Forest, aims for the platform to have superior AI capabilities. This instruction multiplies the individual bytes of two unsigned or unsigned source operands, then adds and accumulates the results into the destination dword element size operand. The bit definition: CPUID.(EAX=7,ECX=1):EDX[bit 4] AVX-VNNI-INT8 is on a new feature bits leaf. Add a CPUID feature word FEAT_7_1_EDX for this leaf. Add CPUID definition for AVX-VNNI-INT8.
