-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

-offsets in addresses.  Thus sorting to put the smallest address first
-allows the most combinations to be found.
