tree-optimization/97897 - complex lowering on abnormal edges
This fixes complex lowering to not put constants into abnormal
edge PHI values by making sure abnormally used SSA names are
VARYING in its propagation lattice.

* tree-complex.c (complex_propagate::visit_stmt): Make sure
abnormally used SSA names are VARYING.
(complex_propagate::visit_phi): Likewise.
* tree-ssa.c (verify_phi_args): Verify PHI arguments on abnormal
edges are SSA names.
* gcc.dg/pr97897.c: New testcase.
