* dependency.c (check_section_vs_section): Pre-calculate
the relationship between the strides and the relationship
between the start values. Use an integer constant one for
that purpose.
Forward dependencies for positive strides apply for where
the lhs start <= rhs start and lhs stride <= rhs stride
and vice versa for negative stride. No need to compare
end expressions in either case (assume no bounds violation).
