Description Li Feng 2009-03-29 08:39:30 UTC
in build_sese_loop_nests, the loops in sese->loop_nest can be:
loop3 loop2 loop1(test case: gcc.dg/graphite/block-3.c), after 
the algorithms(sort the loops) there,
it will still unordered as loop2 loop1 loop3.

I'm not sure if this is the bug. but if this bug is confirmed, 
I will take care of this.
