* tree-ssa-loop-niter.c (idx_infer_loop_bounds): Add and use
argument "reliable".
(infer_loop_bounds_from_ref, infer_loop_bounds_from_array):
Add argument "reliable". Propagate it through calls.
(infer_loop_bounds_from_undefined): Derive number of iterations
estimates from references in blocks that do not dominate loop latch.
(gcov_type_to_double_int): New function.
(estimate_numbers_of_iterations_loop): Use gcov_type_to_double_int
and expected_loop_iterations_unbounded.
* cfgloopanal.c (expected_loop_iterations_unbounded): New function.
(expected_loop_iterations): Use expected_loop_iterations_unbounded.
* tree-data-ref.c (estimated_loop_iterations): Export.
(get_references_in_stmt): Fix -- do not return addresses of local
objects.
* cfgloop.h (expected_loop_iterations_unbounded,
estimated_loop_iterations): Declare.
