    Replace ad-hoc value_range dumpers with irange::dump.
    
    This causes a regression in gcc.c-torture/unsorted/dump-noaddr.c.
    
    The test is asserting that two dumps are identical, but they are not
    because irange dumps the type which varies between runs:
    
                   <          VR  [irange] void (*<T3dc>) (int) [1, +INF]
                   >          VR  [irange] void (*<T3da>) (int) [1, +INF]
    
    I have changed the pretty printer for irange types to pass TDF_NOUID,
    thus avoiding this problem.
    
    gcc/ChangeLog:
    
            * ipa-prop.cc (ipa_print_node_jump_functions_for_edge): Use
            vrange::dump instead of ad-hoc dumper.
            * tree-ssa-strlen.cc (dump_strlen_info): Same.
            * value-range-pretty-print.cc (visit): Pass TDF_NOUID to
            dump_generic_node.
