Clang 6.0.0 will undefine function _mm512_maskz_set1_epi64 on i686
target. Fix it by replacing the function with _mm512_set4_epi64 when
doing 32-bit build.
Warning message during build:
../drivers/net/virtio/virtio_rxtx_packed_avx.c:385:19: warning:
implicit declaration of function '_mm512_maskz_set1_epi64' is invalid
in C99 [-Wimplicit-function-declaration]

Optimize packed ring Tx path like Rx path. Split Tx path into batch and
single Tx functions. Batch function is further optimized by AVX512
instructions.

Optimize packed ring Rx path with SIMD instructions. Solution of
optimization is pretty like vhost, is that split path into batch and
single functions. Batch function is further optimized by AVX512
instructions.
