tree-optimization/103458 - avoid creating new loops in CD-DCE
When creating forwarders in CD-DCE we have to avoid creating loops
where we formerly did not consider those because of abnormal
predecessors. At this point simply excuse us when there are any
abnormal predecessors.

* tree-ssa-dce.c (make_forwarders_with_degenerate_phis): Do not
create forwarders for blocks with abnormal predecessors.
* gcc.dg/torture/pr103458.c: New testcase.
