[Bug tree-optimization/39761] data-flow analysis does not discover constant real/imaginary parts

Ok, doesn't work.  We get lattice transitions CONSTANT -> CONSTANT with
different
values which is unexpected (or even may break sth).  If you remove that sanity
check it substitutes the broken constant (huh, with zero!) (checks missing for
that), but otherwise the propagation itself works.

Too much of a hack... ;)
