Detailed Description

Information about a unique "increment" associated with candidates
   having an SSA name for a stride.  An increment is the difference
   between the index of the candidate and the index of its basis,
   i.e., (i - i') as discussed in the module commentary.

   When we are not going to generate address arithmetic we treat
   increments that differ only in sign as the same, allowing sharing
   of the cost of initializers.  The absolute value of the increment
   is stored in the incr_info.
