Actually what is happening here is that abnormal edges are put into their own basic
block which is done on purpose to speed up the compiler's DCE and DOM, I do not think
this was not done on acident, it was done as part of a design of the pass which causes
this. I think this will be fixed on the tree-ssa though iff Steven B.'s DCE goes in.
