[Bug c/37485] New: [graphite] Disconnecting exit edge in process of code generation

[harsha dot jagasia at amd dot com]

In tranlate_clast when clast stmt is a stmt_user, we can end up disconnecting
the edge that is the exit_edge of the scop that is transformed. This state
creates problems because the exit_edge no longer has a destination. Hence when
after translate_clast, the exit_edge is redirected with redirect_edge_succ, the
edge is already disconnected.
