We don't do insertion because the redundancy is not along an edge that
is supposed to be optimize_edge_for_speed_p (). But frequencies and
counts are the same as on the 4.5 branch!? So it's probably the
optimize_function_for_size_p (main) issue again... I wonder how many
wrong-code tortures no longer test what they used to test because of
this ...
Marking main () with attribute((hot)) makes PRE functional again.
Honza, I think the testing issue is a real problem for existing testcases.
