tree-optimization/121829 - bogus CFG with asm goto
When the vectorizer removes a forwarder created earlier by split_edge
it uses redirect_edge_pred for convenience and efficiency. That breaks
down when the edge split is originating from an asm goto as that is
a jump that needs adjustments from redirect_edge_and_branch. The
following factores a simple vect_remove_forwarder handling this
situation appropriately.
PR tree-optimization/121829
* cfgloopmanip.cc (create_preheader): Ensure we can insert
at the end of a preheader.
* gcc.dg/torture/pr121829.c: New testcase.
