Packit 6c4009 
	   to find out if any byte in xword could be zero. This is fast, but
Packit 6c4009 
	   also gives false alarm for any byte in range 0x81-0xff. It does
Packit 6c4009 
	   not matter for correctness, as if this test tells us there could
Packit 6c4009 
	   be some zero byte, we check it byte by byte, but if bytes with
Packit 6c4009 
	   high bits set are common in the strings, then this will give poor
Packit 6c4009 
	   performance. You can #define EIGHTBIT_NOT_RARE and the algorithm
Packit 6c4009 
	   will use one tick slower, but more precise test
Packit 6c4009 
	   ((xword - 0x0101010101010101) & (~xword) & 0x8080808080808080),
Packit 6c4009 
	   which does not give any false alarms (but if some bits are set,
Packit 6c4009 
	   one cannot assume from it which bytes are zero and which are not).
Packit 6c4009 
	   It is yet to be measured, what is the correct default for glibc
Packit 6c4009 
	   in these days for an average user.
