* 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.
