tree-optimization/103219 - avoid ICE in unroll-and-jam
For no particularly good reason unroll-and-jam uses single_dom_exit
to determine the exit for the region it wants to run VN on. That
happens to ICE because of the dominance restriction. Use single_exit
instead.

* gimple-loop-jam.c (tree_loop_unroll_and_jam): Use single_exit
to determine the exit for the VN region.
