Does hardware on which negative stride is faster really exists?
Depends on what the alterntive is.
For a Fortran assignment
a(n1:n2) = a(n3:n4)
the semantics of the language demand that the RHS is evaluated
completely before the assignment. In the case of the wrong
kind of overlap, a negative stride can be used instead of
using an array temporary.
