builtins.c (expand_builtin_apply): Pass proper parameters to allocate_dynamic_stack_space.

	* builtins.c  (expand_builtin_apply):  Pass proper parameters to
	allocate_dynamic_stack_space.
	* calls.c (emit_call_1):  Do not adjust stack pointer for SIB,
	update stack_pointer_delta; do not update arg_size_so_far.
	(compute_argument_block_size): Use stack_delta instead of
	stack_pointer_pending and arg_size_so_far.
	(expand_call): Add sanity checking for stack_pointer_delta;
	save and restore stack_pointer_delta for SIB, use
	stack_pointer_delta for alignment; do not update arg_space_so_far.
	(emit_library_call_value): Use stack_pointer_delta for alignment.
	(store_one_arg): Do not update arg_space_so_far.
	* explow.c (adjust_stack, anti_adjust_stack): Update
	stack_pointer_delta.
	(allocate_dynamic_stack_space): Add sanity checking for
	stack_pointer_delta.
	* expr.c (init_expr, clear_pending_stack_adjust): Clear
	stack_pointer_delta.
	(emit_push_insn): Update stack_pointer_delta.
	* function.h (struct expr_status): Add x_stack_pointer_delta;
	remove x_arg_space_so_far.
	(arg_space_so_far): Remove.
	(stack_pointer_delta): New macro.
