The ino64 mount option adds a fixed offset to 32bit inode numbers
to bring them into the 64bit range.  There's no need for this kind
of debug tool given that it's easy to produce real 64bit inode numbers
for testing.

Actually test with a large enough device and let them spread evenly
over the AGs.

It's the large-enough device which sometimes is at odds with "easy"
