The only way i can see this happening is if you have a truly
uninitialized variable, or there is something we have missed.
Does this function have cfun->static_chain_decl being used, and we
have a copy of that here?
It is theoretically safe to call set_ssa_to_val with to == vn_top, but
it's probably a bug somewhere, and i'd rather eliminate the bug cases
before turning it off.
