* tree-data-ref.c (dr_analyze_indices): Do not set
DR_UNCONSTRAINED_BASE.
(dr_may_alias_p): All indirect accesses have to go the
formerly DR_UNCONSTRAINED_BASE path.
* tree-data-ref.h (struct indices): Remove
unconstrained_base member.
(DR_UNCONSTRAINED_BASE): Remove.
* gcc.dg/torture/pr62031.c: New testcase.
