tree-ssa-dom.c (nonzero_vars_stack, [...]): New global varrays to replace the block local varrays.

	* tree-ssa-dom.c (nonzero_vars_stack, vrp_variables_stack): New
	global varrays to replace the block local varrays.
	(struct dom_walk_block_data): Remove, no longer used.
	(get_eq_expr_value): No longer need to pass around pointers to local
	varrays.  Callers updated.  Unused markers added to unused parameters.
	(record_range, record_equivalences_from_stmt): Likewise.
	(record_equivalences_from_incoming_edge): Likewise.
	(record_var_is_nonzero): Likewise.  Update now that we have a
	single global varray of SSA_NAMEs that need restoring.
	(dom_opt_initialize_block_local_data): Kill, no longer used.
	(tree_ssa_dominator_optimize): Initialize new global varrays.
	Update callbacks in dominator walker structure.
	(dom_opt_initialize_block): Add markers to NONZERO_VAR_STACK and
	VRP_VARIABLES_STACK.
	(restore_nonzero_vars_to_original_value): Update now that we have
	a single global varray of SSA_NAMEs that need restoring.
	(dom_opt_finalize_block): Similarly for VRP_VARIABLES_STACK.
	Remove unused variables.
	(optimize_stmt): Remove unused variable.
