Calculate s1 - s2 for the n bytes after s1 and s2 and stop when the difference is not 0.
INPUTS
s1, s2 - Begin of the memory areas to compare
n

RESULT
The difference of the memory areas. The difference is 0, if both are equal, < 0 if s1 < s2 and > 0 if s1 > s2. Note that it may be greater then 1 or less than -1.
