I think you want to test if y enables pure_const prior calling get
becuase get_create will just create empty info that will likely have
IPA_CONST (which is 0) and not IPA_NEITHER. There are multiple copies
of this code in other propagators and I think they all needs to check if
the pass is enabled for particular symbol and if not resort to
propagating nothing.
