Do not allow irreducible loops/regions in a scop
Irreducible regions are not going to be optimized by ISL
so discard them early. Passes bootstrap and regtest.
gcc/ChangeLog:
2015-11-06 Aditya Kumar <aditya.k7@samsung.com>
* graphite-scop-detection.c (scop_detection::merge_sese): Entry and exit edges should not be a part of irreducible loop.
(scop_detection::can_represent_loop_1): Loops should not be irreducible.
(scop_detection::harmful_stmt_in_region): All the basic block should belong to reducible loops.
