[Bug tree-optimization/22401] DOM messes up the profiling info

DOM seems to be innocent here.  Before DOM the header is copied and DOM notice that loop
is infinite when entered.  There is no sane way to represent infinite loop in profile
(ie it's frequency would have to be either infinity or 0) so without rescaling the rest we can't really do much.
