+Since SSA names do leak into global tree data structures like
+TYPE_SIZE or in this case GFC_DECL_SAVED_DESCRIPTOR because of
+frontend bugs we have to be careful to wipe references to the
+CFG when we deconstruct SSA form because we now do ggc_free that.

+Bootstrapped and tested on x86_64-unknown-linux-gnu, pushed.
