Detailed Description

Describes the evolutions of indices of the memory reference.  The indices
  are indices of the ARRAY_REFs, indexes in artificial dimensions
  added for member selection of records and the operands of MEM_REFs.
  BASE_OBJECT is the part of the reference that is loop-invariant
  (note that this reference does not have to cover the whole object
  being accessed, in which case UNCONSTRAINED_BASE is set; hence it is
  not recommended to use BASE_OBJECT in any code generation).
  For the examples above,

  base_object:        a                              *(p + x + 4B * j_0)
  indices:            {j_0, +, 1}_2                  {16, +, 4}_2
               4
               {i_0, +, 1}_1
               {j_0, +, 1}_2
