EVERY_ITERATION parameter.
(number_of_iterations_exit): Check if exit is executed every
iteration.
(idx_infer_loop_bounds): Similarly here.
(n_of_executions_at_most): Simplify
to only test for cases where statement is dominated by the
particular bound; handle correctly the "postdominance"
test.
(scev_probably_wraps_p): Use max loop iterations info
as a global bound first.
