PR tree-optimization/19210
* common.opt (Wunsafe-loop-optimizations, funsafe-loop-optimizations):
New.
* Makefile.in (tree-ssa-loop-niter.o): Depend intl.o.
* loop-iv.c (get_simple_loop_desc): If -funsafe-loop-optimizations,
rely on unproven assumptions.
* predict.c (predict_loops): Adjust call to number_of_iterations_exit.
* tree-flow.h (number_of_iterations_exit): Add final parameter.
* tree-scalar-evolution.c (number_of_iterations_in_loop): Adjust call
to number_of_iterations_exit.
* tree-ssa-loop-ivcanon.c (empty_loop_p): Likewise.
* tree-ssa-loop-ivopts.c (niter_for_exit): Likewise.
* tree-ssa-loop-niter.c (find_loop_niter,
estimate_numbers_of_iterations_loop): Likewise.
(number_of_iterations_exit): Honor the new options.
* doc/invoke.texi (Wunsafe-loop-optimizations,
funsafe-loop-optimizations): Document them.
