PR tree-optimization/52406
* tree-data-ref.h: Update documentation about DR_BASE_OBJECT.
(struct indices): Add unconstrained_base member.
(struct dr_alias): Remove unused vops member.
(DR_UNCONSTRAINED_BASE): New define.
* tree-data-ref.c (dr_analyze_indices): For COMPONENT_REFs
add indices to allow their disambiguation. Make DR_BASE_OBJECT
be an artificial access that covers the whole indexed object,
or mark it with DR_UNCONSTRAINED_BASE if we cannot do so. Canonicalize
plain decl base-objects to their MEM_REF variant.
(dr_may_alias_p): When the base-object of either data reference
has unknown size use only points-to information.
(compute_affine_dependence): Make dumps easier to read and
more verbose.
* tree-vect-data-ref.c (vector_alignment_reachable_p): Use
DR_REF when looking for packed references.
(vect_supportable_dr_alignment): Likewise.
* gcc.dg/torture/pr52406.c: New testcase.
