(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.
