* emit-rtl.c (try_split): Update mark_jump_label call.

	* flow.c (find_sub_basic_blocks): Likewise.
	* jump.c (cross_jump_death_matters, find_cross_jump, do_cross_jump,
	jump_back_p): Kill.
	(mark_all_labels): Kill second parameter.
	(jump_optimize, jump_optimize_1): Kill cross_jump parameter.
	(rebuild_jump_labels, jump_optimize_minimal): Update call
	of jump_optimize_1.
	(jump_optimize_1): Kill crossjumping code.
	(mark_jump_label): Kill cross_jump parameter.
	* rtl.h (mark_jump_label, jump_optimize): Update prototypes.
	(JUMP_CROSS_JUMP, JUMP_CROSS_JUMP_DEATH_MATTERS): Kill.
	* reg-stack.c (reg_to_stack): Do not rebuild if not needed; do
	 splitting.
	* toplev.c (enum dump_file_index): Kill DFI_jump2; put DFI_stack before
	DFI_bpro.
	(rest_of_compilation): Update calls to jump_optimize; kill jump2 pass;
	reorganize passes to do reg-stack first, bb-reorder second.
	* invoke.texi (-d letters doc): Remove the jump2 pass.
