In some cases, the strength reduction optimization pass can produce better
code if this is defined. This macro controls the order that induction
variables are combined. This macro is particularly useful if the target has
limited addressing modes. For instance, the SH target has only positive
offsets in addresses. Thus sorting to put the smallest address first
allows the most combinations to be found.
