* cfgloopmanip.c (duplicate_subloops): Export.
* tree-parloops.c (loop_parallel_p): Dump if loop is innermost.
(transform_to_exit_first_loop): Duplicate bbs starting from
header up to loop->latch instead of exit->src.
Initialize control variable to the correct number of iterations.
(gather_scalar_reductions): Do not register double reductions.
(parallelize_loops): Dump which loop is tested.
Indicate whether the parallelized loop is inner or not.
Remove the innermost-loop requirement.
* cfgloop.h (duplicate_subloops): Export.
* tree-cfg.c (add_phi_args_after_redirect): New function.
(gimple_duplicate_sese_tail): Remove the no-subloops constraint.
Call duplicate_subloops.
Update number of iterations at the exit condition.
Don't redirect nexits always to the loop exit.
Redirect copied edges from latch to the loop exit.
* testsuite/libgomp.graphite/force-parallel-2.c: Adjust scan.
* testsuite/gcc.dg/autopar/outer-1.c: New testcase.
* testsuite/gcc.dg/autopar/outer-2.c: New testcase.
* testsuite/gcc.dg/autopar/outer-3.c: New testcase.
* testsuite/gcc.dg/autopar/outer-4.c: New testcase.
