* tree-ssa-loop-niter.c (number_of_iterations_lt_to_ne,
assert_no_overflow_lt, assert_loop_rolls_lt,
number_of_iterations_lt, number_of_iterations_le,
number_of_iterations_cond, number_of_iterations_exit):
Use integer_zerop/integer_nonzerop instead of
null_or_integer_zerop/nonnull_and_integer_nonzerop.
* tree.h (null_or_integer_zerop, nonnull_and_integer_nonzerop):
Removed.
* tree-scalar-evolution.c (simple_iv): Return zero for step of
an invariant.
* tree-ssa-loop-ivopts.c (alloc_iv): Do not set step of invariants
to zero.
(get_iv): Return NULL for non-scalar types. Use zero as a step
of an invariant.
(determine_biv_step, find_interesting_uses_op,
find_interesting_uses_cond, find_interesting_uses_stmt,
add_old_ivs_candidates, determine_use_iv_cost_condition,
rewrite_use_compare, remove_unused_ivs):
Use integer_zerop instead of null_or_integer_zerop.
(struct ifs_ivopts_data): Replace step_p field with step field.
(idx_find_step): Use zero as a step of an invariant. Modify
step instead of *step_p.
(find_interesting_uses_address): Use zero as a step of an invariant.
Use integer_zerop instead of null_or_integer_zerop.
(find_interesting_uses_outside): Call find_interesting_uses_op only
for phi nodes for real operands.
(add_candidate_1): Expect step to be non-NULL.
* tree-ssa-loop-prefetch.c (idx_analyze_ref): Expect step to be
non-NULL.
