re PR tree-optimization/82397 (qsort comparator non-negative on sorted output: 1 in vect_analyze_data_ref_accesses)

2017-10-06  Richard Biener  <rguenther@suse.de>

PR tree-optimization/82397
* tree-vect-data-refs.c (dr_group_sort_cmp): Do not use
operand_equal_p but rely on data_ref_compare_tree for detecting
equalities.
(vect_analyze_data_ref_accesses): Use data_ref_compare_tree
to match up with dr_group_sort_cmp.

* gfortran.dg/pr82397.f: New testcase.
