middle-end/98638 - avoid SSA reference to stmts after SSA deconstruction
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.
