	* tree-ssa-loop-ivcanon.c (tree_estimate_loop_size): Add edge_to_cancel
	parameter and use it to estimate code optimized out in the final iteration.
	(loop_edge_to_cancel): New function.
	(try_unroll_loop_completely): New IRRED_IVALIDATED parameter;
	handle unrolling loops with bounds given via max_loop_iteratins;
	handle unrolling non-inner loops when code size shrinks;
	tidy dump output; when the last iteration loop still stays
	as loop in the CFG forcongly redirect the latch to
	__builtin_unreachable.
	(canonicalize_loop_induction_variables): Add irred_invlaidated
	parameter; record niter bound derrived; dump
	max_loop_iterations bounds; call try_unroll_loop_completely
	even if no niter bound is given.
	(canonicalize_induction_variables): Handle irred_invalidated.
	(tree_unroll_loops_completely): Handle non-innermost loops;
	handle irred_invalidated.
	* cfgloop.h (unlop): Declare.
	* cfgloopmanip.c (unloop): Export.
	* tree.c (build_common_builtin_nodes): Build BULTIN_UNREACHABLE.
