* cfgloop.h (estimate_numbers_of_iterations_loop): Remove
use_undefined_p parameter.
* tree-flow.h (estimate_numbers_of_iterations): Likewise.
* tree-ssa-loop-niter.c (estimate_numbers_of_iterations_loop):
Likewise.
(estimate_numbers_of_iterations): Likewise.
(estimated_loop_iterations): Adjust.
(max_loop_iterations): Likewise.
(scev_probably_wraps_p): Likewise.
* tree-ssa-loop.c (tree_ssa_loop_bounds): Likewise.
* tree-vrp.c (adjust_range_with_scev): Use max_stmt_executions,
not max_loop_iterations.
(execute_vrp): Remove explicit number of iterations estimation.
