This patch introduces the base, avx and sse optimized zero detect memory function. The zero detect memory function tests if a memory region is all zeroes. If all the bytes in the memory region are zero, the function return a zero. Otherwise, if the memory region has non zero bytes, the zero detect function returns a 1.
