   on pcmpistri to find out if two 16byte data elements are the same
   and the offset of the first different byte.  There are 4 cases:

   1. Both 16byte data elements are valid and identical.
   2. Both 16byte data elements have EOS and identical.
   3. Both 16byte data elements are valid and they differ at offset X.
   4. At least one 16byte data element has EOS at offset X.  Two 16byte
      data elements must differ at or before offset X.

   Here is the table of ECX, CFlag, ZFlag and SFlag for 4 cases:

   case		ECX	CFlag	ZFlag	SFlag
    1		16	  0	  0	  0
    2		16	  0	  1	  1
    3		 X	  1	  0	  0
    4	       0 <= X	  1	 0/1	 0/1

   We exit from the loop for cases 2, 3 and 4 with jbe which branches
   when either CFlag or ZFlag is 1.  If CFlag == 0, we return 0 for
   case 2.  */
