6e2013391a mem: Add zero detect memory functions 
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.
