PR tree-optimization/22236
* tree-cfg.c (print_pred_bbs, print_succ_bbs): Correctly print
successors and predecessors.
* tree-chrec.c (chrec_convert): Before converting, check that
sequences don't wrap.
* tree-data-ref.c (compute_estimated_nb_iterations): Moved ...
(analyze_array): Extern.
(find_data_references_in_loop): Remove call to
compute_estimated_nb_iterations.
* tree-data-ref.h (analyze_array): Declared.
* tree-flow-inline.h (single_ssa_tree_operand, single_ssa_use_operand,
single_ssa_def_operand, zero_ssa_operands): Fix documentation.
* tree-flow.h (scev_probably_wraps_p): Declare with an extra parameter.
* tree-scalar-evolution.c (instantiate_parameters_1): Factor entry
condition.
* tree-ssa-loop-ivcanon.c: Fix documentation.
* tree-ssa-loop-ivopts.c (idx_find_step): Add a fixme note.
* tree-ssa-loop-niter.c (compute_estimated_nb_iterations): ... here.
(infer_loop_bounds_from_undefined): New.
(estimate_numbers_of_iterations_loop): Use
infer_loop_bounds_from_undefined.
(used_in_pointer_arithmetic_p): New.
(scev_probably_wraps_p): Pass an extra parameter. Call
used_in_pointer_arithmetic_p. Check that AT_STMT is not null.
(convert_step): Fix documentation.
* tree-vrp.c (adjust_range_with_scev): Call instantiate_parameters.
Use initial_condition_in_loop_num and evolution_part_in_loop_num
instead of CHREC_LEFT and CHREC_RIGHT. Adjust the call to
scev_probably_wraps_p.
