* tree-ssa-loop-niter.c: Include gmp.h.
(bounds): New type.
(mpz_set_double_int, get_type_bounds, mpz_to_double_int,
split_to_var_and_offset, determine_value_range,
bound_difference_of_offsetted_base, refine_bounds_using_guard,
bound_difference, bounds_add, bounds_negate,
number_of_iterations_ne_max, dump_affine_iv): New functions.
(number_of_iterations_ne, number_of_iterations_lt_to_ne,
assert_loop_rolls_lt, assert_loop_rolls_le): Use bounds on the
difference of initial and final value of control iv to validate
results.
(number_of_iterations_cond): Add loop parameter. Determine bounds
on the difference of the extremes of the control iv. Add dumps.
(expand_simple_operations): Handle phi nodes.
(simplify_using_initial_conditions): Do not record used conditions.
(number_of_iterations_exit): Pass loop to number_of_iterations_cond.
Do not set additional_info.
(implies_nonnegative_p, implies_ge_p): Removed.
(derive_constant_upper_bound): Do not use parameter `additional'.
(record_estimate): Parameter `additional' removed. Parameter
`i_bound' added. Do not call derive_constant_upper_bound.
(record_nonwrapping_iv): Use derive_constant_upper_bound to
bound the number of iterations estimate.
(estimate_numbers_of_iterations_loop): Pass the estimate from
the number of iterations analysis to record_estimate.
* tree.h (multiple_of_p): Declare.
* tree-scalar-evolution.c (expression_expensive_p): Removed.
(scev_const_prop): Do not check expression_expensive_p.
* fold-const.c (multiple_of_p): Exported.
* double-int.c (double_int_mask): Exported.
* double-int.h (double_int_mask): Declare.
* tree-flow.h (struct tree_niter_desc): Removed additional_info
field. Added max field.
* gcc.dg/tree-ssa/loop-26.c: New test.
