* tree-ssa-loop-niter.c (number_of_iterations_exit): New parameter
EVERY_ITERATION with implicit value of true.
(record_estimate): Check dominance relationship of the basic block
we are estimating on instead of relying on UPPER to be false.
(struct ilb_data): Drop RELIABLE.
(idx_infer_loop_bounds): Update.
(infer_loop_bounds_from_ref): Drop parameter RELIABLE.
(infer_loop_bounds_from_array): Drop parameter RELIABLE.
(infer_loop_bounds_from_undefined): Update comments and handling
of RELIABLE.
(estimate_numbers_of_iterations_loop): Record all bounds.
